1. GENERAL INFORMATION

1.1 Introduction In the Netherlands, graduate schools have been founded for a variety of scientific disciplines. Interuniversity graduate schools are schools in which several Dutch universities participate, as laid down in a formal agreement between the Executive Boards of the participating universities. One of the universities is responsible for the daily organization and administration of the graduate school, including the organization of the PhD educational programme and various scientific activities. These activities are conducted under the responsibility of a scientific director, often, but not necessarily, one of the professors of the university that is in charge of the administration. The primary aims of graduate schools are to provide additional education and training for PhD students of the participating institutions and to foster scientific contacts and collaboration. For the Graduate School on Engineering Mechanics the aims have been particularized in the Mission Statement, presented in section 1.2. Graduate schools can be accredited by the Royal Netherlands Academy of Arts and Sciences (KNAW), which gives a mark of quality. The accreditation is given on the basis of a proposal in which a coherent educational program for PhD students is described as well as coherence in terms of research between the participating teams. Accreditation is given for six-year periods. After such a period an application for renewal of the accreditation can be filed at the KNAW, which consists of a self-assessment over the past period, together with a peer review based on a site visit, interviews and this self-assessment. The Graduate School on Engineering Mechanics was founded in 1996 and received a five-year accreditation of the KNAW directly at the first application in 1997. It embraces all research groups that are active in the field at the Eindhoven University of Technology, the Delft University of Technology and the University of Twente, with the Eindhoven University of Technology acting as the commissioner, hosting the secretariat. In 2001 and 2006 a peer review of the activities of the Graduate School over the first and second period of operation by an international review panel took place and in 2002 and 2007 the ECOS/KNAW-accreditation of the Graduate School on Engineering Mechanics was renewed. In 2012 a peer review of the activities of the Graduate School over its third period of operation by an international review panel took place and the Graduate School on Engineering Mechanics has applied for the ECOS/KNAW-accreditation for its fourth period of operation 2013-2019 The Graduate School on Engineering Mechanics represents the internationally active groups of the Dutch universities of technology in the area of engineering mechanics. The EM-school also co-ordinates and tunes the research activities in the participating groups (e.g. through the 3TU Centre of Excellence), and it has developed a complete graduate course programme in collaboration with the JM Burgers Centre (Graduate School on Fluid Mechanics). It can therefore be considered as the representative scientific platform in the Netherlands in the engineering mechanics field. This platform sets the strategic directions of future research in the Netherlands in the engineering mechanics field, and it is responsible for the quality of future generations of PhDs, who are the primary determinants of the quality of future activities in this area in the Dutch industries and universities. In the Graduate School on Engineering Mechanics the individual research groups have an essential responsibility in executing their individual research programs. On basis of consensus, the graduate

6

school thereby stimulates certain focal areas of research. More importantly, it exercises a quality control on the level of research, since it has adopted a lower bound for the quality of the participating groups, which derives from the research assessments at the level of the university departments that are commissioned by the Netherlands Association of Universities (VSNU).

1.2 Mission

The Netherlands Graduate School on Engineering Mechanics has been established with the aim to strengthen research and education in the field of engineering mechanics in The Netherlands. The EM Graduate School intends to be a platform that, on the basis of a number of selected research themes, fosters long-term knowledge and skills in the engineering mechanics field. Although operating primarily at a national level, it intends to stimulate international collaborative research projects within the research themes. Within the foregoing global objectives the following more specific objectives can be formulated:

Training of PhD-students to become qualified independent researchers in the field of engineering mechanics according to international standards. To this end, a series of high-quality graduate courses is developed on specific subjects.

Co-ordination and tuning of the engineering mechanics research activities in the participating groups. Furthermore, the Graduate School aims at strengthening the available infrastructure for research in engineering mechanics. It can be stated that the present infrastructure meets high international standards.

Selection of the main research themes in engineering mechanics carried out within the EM Graduate School. These research themes are being characterized by a strong international

position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society.

Strengthening of the international scientific position and the international visibility of The Netherlands in the engineering mechanics field.

Cooperation with industries and technological institutes to promote the mutual exchange of knowledge on engineering mechanics.

Maintain close connections and cooperate with related fields of engineering.

Stimulate nation-wide thematic discussions, streamlined research strategies and organization of workshops for representatives from industry, technological institutes and project leaders to

discuss the needs of industries with respect to scientific research.

Guarding the standards of undergraduate education in the engineering mechanics area at the Dutch universities. This is done in particular by influencing policies with respect to the

appointment of professors and other senior staff in this area.

Attracting highly qualified engineers, prospective and established scientists to the Netherlands.

1.3 The field of Engineering Mechanics

Engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and mechanical processes. Solid mechanics is at the heart of engineering mechanics, but is not necessarily identical to it. Traditionally, engineering mechanics is one of the fundamental cores of engineering sciences such as Aerospace Engineering, Civil Engineering, Mechanical Engineering and Maritime Technology.

7

Assisted by a steady growth in computational power, resources and efficiency, new challenges and perspectives for the engineering mechanics field have emerged. Contemporary developments of engineering mechanics include the following major directions:

Prediction of structural mechanical behaviour from material mechanics and establishment of structure-property relations for engineering materials and structures, including the ultimate failure of the material or structure. The ultimate aim is to bridge the gap between science and technology in the area of materials processing and design, via computational modelling and experimental analysis of the full thermo-mechanical history of material during their formation, processing and final design, in order to be able to quantitatively predict product properties. This equally applies to structures composed of these materials.

Prediction of the dynamic behaviour of engineering systems with full account of nonlinearities and multiphysical dynamic interaction and experimental identification under operational conditions. This area is of crucial importance in many practical dynamical systems where friction, contact and other nonlinearities have a substantial effect on the dynamic behaviour.

Optimization of products, processes and systems by means of computer simulations to enhance the reliability and to tailor their mechanical behaviour for the particular application. Here, it is assumed that the simulation of the mechanical behaviour can be carried out in a sufficiently accurate way, while the optimal design is traced numerically. Among typical application areas, the following can be highlighted:

miniaturization & micro-technology: design, optimization, processing and functionality of MEMS (micro-electro-mechanical systems) and NEMS (nano-electro-mechanical systems); processing, performance and reliability in SiP (systems in package); low-k solutions in IC-technology; lead-free soldering; …

high-tech consumer applications: flexible displays; flexible photovoltaic cells; lab-on-a-chip systems; RF-MEMS wireless technology; …

high-tech materials: metastable materials; shape memory alloys; TRIP-steels; GLARE; Ni-based superalloys; thermoshock materials; high-temperature engine materials; self-healing materials; thermoplastic composites, …

innovation and optimization in manufacturing: polymer-coated sheet processing in packaging; discrete die forming; damage engineering in metals; paperboard engineering; friction stir welding; …

dynamics of materials and structures: nonlinear control of motion systems and robotics, vehicle dynamics, tire dynamics, acoustics and control, structural acoustics and noise control, structural health monitoring of wind turbines;...

construction engineering: collision-proof ship hulls; damage control in masonry and concrete structures, …

topology optimization of smart structures As a consequence of the above developments, the traditional boundaries between solid and fluid mechanics are sometimes fading. This happens, for example, in fluid-structure interaction (FSI), in the field of mechanics of materials and in the area of acoustic radiation of structures. In addition, the interactions with other areas of engineering sciences, such as materials technology, thermodynamics and systems and control, become of increasing importance. Finally, it is noted that the successful implementation of the abovementioned developments in practical applications relies on prior experimental validation of the developed simulation tools and physical models. This requires an increasing interaction between computational modelling and experimental analysis.

1.6 Research themes

An important goal of the Graduate School on Engineering Mechanics is the co-ordination and combination of research activities of participating groups. In accordance to this it was decided to group the research activities into three research themes: 1. Computational and Experimental Mechanics

This research theme is related to the potential of modern computational and experimental techniques for solving problems in mechanics. Much attention is paid to optimal numerical procedures and to large-scale computing. Important applications are in the field of crash simulation of vehicle systems, simulation of production processes, in particular forming processes, as well as complex structures in civil engineering and aerospace engineering.

2. Structural Dynamics and Control This research theme is related to the dynamic behaviour of engineering structures. Particular attention is paid to nonlinear dynamics and fluid-structure-interaction. Also of importance is the interaction with control. Important applications are in the field of rotating machinery, noise reduction and drive systems.

3. Reliability and Optimization This research theme is related to the development of design procedures based on reliability, as well as to structural optimization with respect to mechanical behaviour. Important applications are in the fields of biomedical technology (e.g. heart valves) and in the field of thin-walled structures.

These research themes fit well with the major directions in contemporary engineering mechanics as described in Section 1.3. Furthermore, they are characterized by a strong international position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society. The different research themes are all characterized by a strong international position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society. Point of departure in all research themes is the development of models based upon the principles of engineering mechanics. These models necessitate and motivate the development of contemporary numerical and experimental tools for solving engineering mechanics problems. The application of these tools in computer-aided design and production processes results in a decrease in the development time of advanced products, and thereby time-to-market, for instance due to a reduction in the required amount of prototypes. Also, an increase in product

11

quality and a reduction in production and operating costs are worth mentioning, improving competitiveness. The optimal use of computational resources for complex numerical simulations as well as the incorporation of nonlinear phenomena in the modeling is common to all three themes

Research groups participate, depending upon their expertise and affinity, in several themes:

1.7 Education

The most important goal of the Graduate School on Engineering Mechanics is the formation and education of graduate students to become independent researchers in the field of Engineering Mechanics. In accordance with this, the Graduate School offers a national four-year training program for PhD students in the field of Engineering Mechanics. It consists of a programmatic part and a PhD research project, accompanied by a personal plan of education and supervision per PhD student. In addition to these joint courses the programmatic part contains an individual course program, with initial and post-initial courses selected from the programs offered at participating groups. Furthermore, participation in workshops and summer schools under guidance of foreign visiting lecturers forms part of it, even as practical work at foreign top-institutes.

12

1.7.1 Course curriculum The PhD research project covers about 80% of the four-years training program. Research topics are in connection with the research program of the Graduate School. As the research approach within the Graduate School is thematically oriented, research students get the opportunity both to deepen their knowledge in the context of their own project and to broaden their vision on the research field as a whole. The programmatic part of the training program covers about 20% of the four years training’s program. The heart of it is formed by a joint series of EM graduate courses, in close connection with the selected research themes. PhD-students are required to take part in at least 50% of the courses, providing the opportunity to keep track with developments in the field of engineering mechanics outside their own focus of research. EM-graduate courses all follow a general framework, which consists of two three-day clusters of lecturing, alternated with (computer) exercises to obtain hands-on experience. In principle, staff members of the participating universities teach the courses, inviting (international) experts in the field as guest lecturers where relevant. The program successfully started in 1998. All courses are evaluated systematically and results are discussed with lecturers and Governing Board. In general, participants are very content with the courses, appreciating their relevance and the new knowledge and information offered. Furthermore, courses enable a fast and effective interaction between research and education. To keep the connection with the selected research themes actual and up-to-date the contents of individual courses is regularly updated. The present courses organized by EM are listed below:

- Continuum thermodynamics

- Optimization and parameter identification

- Nonlinear material mechanics

- Solutions methods in computational mechanics

- Solving Structural Acoustic coupled problems

- Reliability and stability in statics and dynamics

- Mechanics in Microsystems

- Advanced topics in solid mechanics

- Advanced Dynamics

- Experimental engineering mechanics

- Multi-scale and micro-mechanics

- Mechanics in large deformations

13

1.7.2 Structure of the Engineering Mechanics PhD course programme for the period 2009-2013

In 2008, a new course programme has been established in the interest of the PhD students and

Post-Docs. Key characteristics are: a two-years cycle course programme, formal registration of

credit points, more courses and courses of different type (broad or in depth).

Details are provided below:

The minimum educational load for PhD students is 15 credit points (one credit point is equivalent

to one ECTS-credit and will be further referred to as EC), i.e. 1/4 of a year. Every EM PhD student

receives a formal certificate, as proof of his/her successful participation in the EM course

programme.

Boundary conditions:

The courses have to be attended completely. PhD students who only attend a part of a course will not receive credit points for that course.

Each individual has to supply a written proof of the successful completion of a local or external course, to be signed by the supervising professor (promoter).

The EC-equivalent of each course will be determined at 0.5 EC/day.

In order to obtain credit points for an external course that has not been previously approved by EM, the PhD student must request for an approval prior to the start of the course.

In order to obtain the EM certificate, a PhD student must have attended the EM symposium at least 2 times during his PhD contract.

EM will publish a full course calendar on its website.

PhD students who collected a minimum 15 EC, receive a formal certificate, formally handed over during the annual EM symposium.

Outline of the structure of the EM-courses in the programme:

Duration of a cycle in the course programme = 2 years.

Full courses (3 EC): 6 day courses covering the wide scope of key areas in EM. Two such courses are organized every year, i.e. 4 courses in a cycle of 2 years. These courses include a rapid summary of basics followed by advanced topics that are beyond the MSc level.

Topical courses (0.5 or 1 EC): 1- or 2-day courses on specific subjects, for a smaller group of participants. These courses may either strengthen the generic basis or provide specific in-depth knowledge. About 8 such courses are offered in a 2-year cycle.

Recognized courses and allowable share within the programme:

EM-courses and workshops: PhD courses organized by EM (details below). Minimum share = 8 EC.

Recognized external courses organized by external graduate schools or institutes and approved by the EM board

Master courses given at local institutes to patch missing skills in the training of a PhD student, as required for his/her particular project. If MSc courses are taken, the course exam is compulsory and has to be passed. Maximum share = 5 EC

Additional courses such as presentation skills, technical writing, etc. can also be mentioned on the certificate.

14

On request of the PhD student, EM will provide the promotor with a list of the EM-courses he/she

participated in. On the basis of this list and on the request of the PhD student, the promotor can

make a letter stating the full overview of all courses taken in the educational plan of the PhD

student applying for this letter.

EM courses

All EM courses are integral part of a 2-year programme, listed in the sections 1.7.3 (cycle 2012-

2013 and 1.7.4. (Provisional planning cycle 2013-2014)

To design better materials and systems, the mechanical behavior of the material or system in

an application, such as damage or failure, needs to be coupled to the deformation of its

(micro-)structure in order to elucidate the underlying physical deformation mechanisms. To

this end, experimental mechanics seeks to study mechanical deformation through the

measurement of forces and strains (under various loading conditions) and, if possible,

simultaneous visualization of the microstructural deformation. Such an integration of

experimental techniques is often necessary to gain sufficient insight into the complex

deformation mechanisms. This calls for a careful design of the experiment, as well as a

minimum level of understanding of the various existing deformation tests and microscopes in

order to select the appropriate experiment, therefore:

the graduate course on ‘experimental engineering mechanics’ provides an overview of

16

and introduction to commonly-used experimental deformation and visualization

techniques, in which the underlying physical principles will be briefly addressed.

The graduate course will cover lectures by experienced researchers on topics including:

Design of an optimal experiment considering statistical and systematic accuracies and

limitations, also in the context of miniaturization of the experiment, mechanical deformation

tests, including tensile, bending, compression tests, (nano)-indentation, dynamic testing (fatigue,

high speed tests), tribological testing (friction, wear), microscopic techniques for visualizing

deformation, including optical microscopy (different contrast modes), electron microscopy

(including EDX and EBSD), and surface profilometry techniques, as well as digital image correlation

for strain field imaging, and a short individual lab session (performing a bending test under

polarizationmicroscopy).Examples from faculty research and literature will be used to illustrate

possibilities and restrictions of these techniques.

1.8 General description of developments in 2012

2012 was another successful year for the graduate school EM. Like in the previous years priority was laid on the continuation of the research activities in the field of Engineering Mechanics. This resulted in the following overall output for 2012:

Scientific publications: refereed journals 221

Scientific publications: books, chapters in book 20

Scientific publications: refereed proceedings 158

PhD theses 29

* Publications in co-operation between different EM-groups

18

This output is documented in more detail in subsequent chapters of this Annual Report, whereas appendix A contains summaries of the dissertations completed. To stimulate the exchange of information on ongoing research within the Graduate School, the Fifteenth Engineering Mechanics Symposium took place on November 1 and 2, 2012 in congress centre “De Werelt” in Lunteren. One hundred twenty-nine members of the senior academic staff and PhD-students participating within the Graduate School attended the Fifteenth Engineering Mechanics Symposium. Professor prof. D.R.J. Owen presented a keynote lecture, entitled "Fifty Years of Finite Elements: Past Progress and Future Prospects” The topics of the Workshops at the 2012 EM Symposium were “Forming and manufacturing”, ”Large scale computations”, ”Mechatronics” and “Multiscale material mechanics” Each of the workshops started with a Plenary Introduction by the Workshop Organizers on the trends and challenges of the topics of the workshops. Next, two of the actual Workshops were scheduled to run in parallel on the first Symposium day, whereas the other two were scheduled to run in parallel on the second Symposium day. Each Workshop consisted of two parts, separated by a break. Each part consisted of two presentations by PhD-students/Postdocs. In conjunction to the oral presentations there was an PhD-students presentation contest, awarding a prize for the best PhD presentation at each of the Symposium Workshops. Members of the jury were the Workshop Organizers. Winners of the PhD-students presentation contest were: J. van Beeck (TU/e) with a contribution entitled “On the relation between interface roughening and damage in polymer-coated steels”, P. van der Valk (TU/e) with a contribution entitled “Offshore Wind Turbine Design using Dynamic Substructuring”, M. Abel Yaqoob (UT) with a contribution entitled “Pre-sliding behaviour of single asperity contact” and B. Vossen (TU/e) with a contribution entitled “Multi-scale modeling of copper-rubber interface delamination”. In two poster sessions 58 PhD-students of the EM Graduate School presented their current research project. This resulted in stimulating discussions on running projects. In conjunction to the poster sessions a poster contest was organized in which a jury selected the best three contributions. The jury consisted of the following members : Dr.ir. M. (Matthijs) Langelaar, Dr ir. P. (Peter) van den Berg (Deltares), prof.dr. ir.I. (Ines) Lopez Arteaga(TU/e), Dr. ir. M.A.( Marc) Masen (UT). Winners of the poster contest were: E. Hooijkamp (TUD) with the poster “Observation of a thermal Mode and its Time Constant”, J. Hol (UT) with the poster “Metamodeling for active production control“ and N. Irani (TU/e) with the poster “A Discrete Dislocation Analysis of Hydrogen Embrittlement”. The contributed posters are published in an information brochure. The winning contributions can be found on the EM website http://www.em.tue.nl/history/index.php/6 Additional remarks:

The Annual Report 2011, with information on participating research groups, was published in 2012. It was distributed among participants and relations of the Graduate School.

http://www.em.tue.nl/history/index.php/6

There was a meeting of the Advisory Board of the Graduate School on Engineering Mechanics on November 2, 2012, which took place after the Fifteenth Engineering Mechanics Symposium. At this meeting the future strategy and directions of the EM Graduate School were discussed.

There was a meeting of the board of project leaders on November 2, 2012, in which the EM activities were evaluated and the Fifteenth Engineering Mechanics Symposium was discussed. Plans for the Sixteenth Engineering Mechanics Symposium, to be held 28-29 October, 2013 in De Werelt in Lunteren, were also discussed with all faculty members present. The planned workshop topics for 2013 are: “Biomechanics and Biomaterials”, “Discrete and Particle Methods”, “Dynamics, Vibrations and Acoustics”, and“ Micromechanics”.

In 2012, a peer review was organized on the EM-period 2007-2012. The Peer Review Committee wrapped up its conclusion in a report, which is in great support of the graduate school, its activities and organization. On the basis of this peer review, EM applied for a re-accrediation for the period 2013-2019 at KNAW (ECOS). KNAW will decide in 2013.

1.9 Memberships: 1.9.1 Memberships

Regular Membership – Group based

The regular membership of the Graduate School Engineering Mechanics is based on the

admittance of a 3TU research group to become a group member of the School. The membership

of a group is based on three criteria:

Research programme of the group:

The programme should fit in the mission of the EM graduate school and there needs to be a

solid basis for co-operation between the scientific group members and other members in the

graduate school. The group’s research programme must have a critical mass that lies well

within EM’s scope.

Scientific performance and quality:

A new research group can be admitted to EM: (1) on the basis of a proven scientific track

record that underpins the quality of the group leader and faculty members, for a group with

established scientists; (2) on the basis of good expectations for scientific quality and

performance for the group leader and faculty members for a new (young) group. If a new EM

group has previously been assessed by QANU, the requirements outlined in section 4.3 for

existing member-groups apply for the new group as well.

Expectation for integration in the graduate school:

The integration of a new group within EM implies an active participation in the execution of

EM’s PhD course programme and a regular participation of PhD students in the courses

offered by EM. Group members are expected to participate in the annual EM symposium to

present their scientific progress in the oral and poster sessions.

20

Group based members of EM either fall in one of the following categories:

Faculty members

Faculty members are junior (assistant professor) or senior (associate or full professor)

researchers appointed at the research groups by one of the respective universities. They have

a prime responsibility in supervising the PhD students and Post-Docs during their research

projects, and in assisting all PhD students during their PhD educational programme. A high

quality of the supervision is one of the key requirements. Faculty members from an EM

research group can be voluntary member of EM if their research focus fits in the EM research

programme. As a member of the Graduate School EM, faculty members are expected to

actively contribute to the knowledge dissemination (PhD course programme) and knowledge

exchange (EM symposium).

Post-Docs

Post-Docs are young researchers with a PhD degree, who actively contribute to research

projects in the participating research groups. They can take benefit of the EM course

programme and they are expected to participate and contribute to the yearly EM symposium.

They can also play an active role in the Graduate school, by assisting in the PhD educational

programme.

PhD students

PhD students are the research members of the Graduate school, aiming to obtain a PhD with

the support of the Graduate School and the educational part thereof. The PhD projects are

proposed by the supervisors and typically fit within the scope of the EM research topics. PhD

students belonging to member groups are admitted to the Graduate School on proposal of

one of the supervising faculty members (also EM member). They are expected to fully attend

the EM course programme for 15 ECTS and they are expected to participate and contribute to

the yearly EM symposium.

The membership of a group involves a yearly financial contribution, and an individual (small)

contribution to the EM-symposium. The group and individual fees will be determined yearly by

the governing board of the Graduate School. For the yearly fee, full access to the educational

programme for all subscribed group members is granted.

MSc student membership

Excellent MSc students from an EM research group (i.e. an EM group membership as defined in

section 1.1 applies) that are following a MSc-PhD Graduate programme or who have been

identified as potential PhD students in the master phase already, can be admitted as a MSc

student member of the EM Graduate School. These students need to be registered in one of the

adhering Master programmes of the EM graduate school. MSc student members can be admitted

to the Graduate School upon nomination of the MSc/PhD supervisors (EM members). Admittance

implies that MSc student members are allowed to participate in the EM PhD educational

programme and the EM symposium.

21

Associate Membership – Individually based

Individual faculty members who are not part of an EM research group (as defined in section 1.1)

can be admitted to the Graduate School as an associate member. They can also propose a

maximum of 2 PhD students or Post-Docs to become an associate (PhD student or Post-Doc)

member. Note that only 1 faculty member from a group can be an associate member. A larger

participation in EM necessitates a group membership. Associate members of EM can be (1)

researchers from a non-EM research group of 3TU, (2) researchers from Dutch non-3TU research

groups that have an established scientific track record of high quality in engineering mechanics or

(3) established researchers of high quality from a non-Dutch group.

The associate membership implies that Associate members can participate in all EM events,

including its educational programme. Associate members (faculty, Post-Doc or PhDs) have to

contribute financially to the activities (including EM courses) in which they participate.

Industrial Membership

Companies and institutes with long-term research activities in the field of the Graduate School

can request an industrial membership of the Graduate School Engineering Mechanics. The

industrial membership grants full and free access to all courses of the EM course programme for

research employees working in the company. Moreover, as an industrial member, researchers

from these companies or institutes can attend the EM symposium, where they can also actively

participate in the poster sessions. For registration at the symposium, the EM-researchers regular

fee has to be paid.

The industrial membership of a company or research institute involves a yearly financial

contribution, and the individual contribution for participation to the EM-symposium. The level of

the company and individual symposium fees are determined yearly by the governing board of the

Graduate School.

1.9.2 Selection, admission criteria and procedures

Group membership

A group membership is granted by the Board of the Graduate School. The group leader sends a

written motivated request to the scientific director. The Board decides on the basis of all criteria

and arguments provided. Once the group is admitted to EM, all group members (faculty, PhDs,

Post-Docs) can subscribe to EM by completing the form (in attachment). The subscription forms

of PhD students and Post-Docs must be approved and signed by the direct project supervisors.

MSc student membership

Excellent master students, who wish to become an MSc student member, can fill in a subscription

request. This request needs a separate motivation from the responsible supervisors,

accompanied by a list of course marks obtained in the MSc course programme. The scientific

director decides on the basis of all information provided.

22

Associate membership

An associate membership is also granted by the Board of the graduate school. A formal request

has to be sent to the scientific director. The Board decides on the basis of the established

contacts with EM members, the embedding, expected integration and contribution to the EM

graduate school.

Industrial membership

An industrial membership can be granted by the Board of the Graduate School to companies or

research institutes with a strong interest for the EM research activities. To this purpose, the

company or institute sends a written motivated letter to the scientific director. The Board

decides on the basis of all criteria and arguments provided. Once a company or institute is

admitted to EM, its research employees can freely participate in the course activities of the

Graduate School.

1.9.3 Double memberships

Faculty members

Faculty members can be member of more than 1 graduate school. They are nevertheless

expected to play a substantial and active role in each of the graduate schools in which they

participate. To be admitted to a graduate school, at least 25% of the research activities should fit

in EM’s research programme.

PhD students and Post-Docs

Researchers (PhD students and Post-Docs) can be member of one graduate school only (KNAW

requirement).

1.9.4 Quality monitoring & control

Quality expectations

The Engineering Mechanics graduate school expects all its group members and associate

members to aim for a contribution to a high quality research programme. This includes high

quality publications with a good citation impact, keynote lectures, patents or inventions, editorial

roles in international journals, memberships of international assessment committees, etc. In

terms of PhD supervision, a good progress monitoring procedure is expected. It is the prime

responsibility of the group leader to work towards these goals.

Independent assessment

Every 6 years, the quality of the research programmes is assessed by QANU. All research

programmes are evaluated in terms of quality, quantity, relevance and viability. The outcome of

this assessment constitutes the prime feedback on the quality of the research programmes. The

quality of the PhD supervision is monitored through direct feedback from PhD students, either

individually or through the PhD student board.

23

Monitoring

As a minimum threshold for scientific quality, the QANU marks for quality, quantity, relevance

and viability, according to the most recent version of the SEP protocol, have to be at least 3, 3, 3,

3, respectively.

In case a research group underperforms as apparent from the QANU assessment its membership

will be reconsidered by the EM Board. If the supervision of an individual PhD student lacks

quality, the EM management team will directly contact the responsible supervisors to address

the problem.

1.9.5 Additional provision

All situations for which this regulation does not apply will be handled by the Governing Board of

the Graduate School.

1.12 Overview of co-operation

1.12.1 Internal co-operation

With reference to its mission statement the Graduate School on Engineering Mechanics fosters the co-operation between participating research groups. This has resulted in an increasing number of joint research projects that received substantial input from different EM-groups. Joint projects for 2012 are summarized in Appendix C. Furthermore, co-operation between members from different participating groups resulted in a total of 10 joint publications in refereed journals and proceedings.

26

1.12.2 External co-operation

Within the field of mechanics of materials, the Graduate School on Engineering Mechanics strongly co-operates with one of the four leading technological institutes, namely the Materials Innovation Institute (M2i). The EM projects in this institute form a coherent program that concentrates on forming processes and on the fundamental understanding and the predictive analysis of a number of carefully selected generic industrial problems. The main challenge within this program is the accurate prediction of mechanical properties of metals with complex microstructures, in view of their application in micro-systems (functional materials) and various engineering manufacturing processes. Establishing micro-macro structure-property relations with a particular emphasis on the improvement of materials, processes and products at various scales, is thereby a key issue tackled both experimentally and numerically. The scientific work in this area directly supports the long-term strategy of the industrial partners involved (Akzo-Nobel, Boal, Tata Steel, DAF, Dow, DSM, Filarc Welding, GE Plastics, Impress Metal Packaging, Montell, Interturbine, Koninklijke Schelde Groep, Océ, Philips, Polynorm, Reynolds Aluminium, Shell, SKF, Stork, TNO, NLR, NRG) by acquiring fundamental insight that leads to improved materials and processes. At the same time, the investigated applications in several projects are fine-tuned to a particular industrial request, which provides direct answers to specific engineering questions in industry. The EM Graduate School participates in this leading technological institute with 2 clusters (cluster 1 on ‘Virtual shaping and structural performance’ and cluster 2 on ‘Multi-scale fundamentals of materials’). More than 20 EM research projects were initiated within M2i, contributing to the overall EM output. The Graduate School on Engineering Mechanics also co-operates with other universities, research institutes and various industrial partners. External Co-operation: Education With respect to education the EM Graduate School co-operates with other Graduate Schools. It has been agreed that the PhD Students of the EM and JMBC (fluid mechanics) Graduate Schools will be enabled to follow each other’s courses. The same holds for PhD students of the EM Graduate School and the Belgian National Graduate School in Mechanics (GraSMech).

1.13 External developments related to EM

The research schools Engineering Mechanics (Solids) and J.M. Burgers Centre (Fluids) jointly compose the 3TU Centre of Competence of Fluids and Solids, in which the 3TU Centre of Excellence (CoE) for Multiscale Phenomena is embedded. There is a long tradition of co-operation between the two research schools. The 3TU Centre of Excellence for Multiscale Phenomena is the joint excellence centre of EM and JMBC, supported by 3TU. The organizational structure of the research schools and their embedding in 3TU and the Netherlands is shown in the scheme below. At the international level, the two research schools are represented by the Netherlands Mechanics Committee (NMC), through which all formal communication with international scientific organisations (IUTAM, IACM, EUROMECH, etc.) flows.

The financial support of 3TU for the development of the CoE Multiscale Phenomena has been

mainly materialized through new full professor chairs at each TU. At the start of 2010, all 5

planned full professors have been appointed, among which 2 professors (at least partially)

involved in EM (van Brummelen, Luding). Moreover, 4 part-time professors have been appointed.

The graduate programme of NWO is attracting more and more attention and several universities are now also considering to professionalize the PhD education phase for all PhD training programmes. EM has its PhD education phase well in place, and may associated swiftly with new upcoming initiatives. Moreover, EM and JMBC started a NWO graduate programme Fluid and Solids Mechanics. The research programme of the joint EM-JMBC graduate programme is composed of the core research areas in Fluid and Solid Mechanics. The Solids pillar in engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and processes. Solid mechanics is at the heart of engineering mechanics, through which it plays a vital role in economy and society. The Fluids pillar is concerned with the description, analysis and optimization of fluid flows. It is at the heart of phenomena in our environment and is important for a multitude of industrial, biomedical and environmental processes. The interaction between fluids and solids in many engineering problems across the scales, constitutes a natural common part between both disciplines. Solid and Fluid Mechanics play a significant role in many areas of applications that are relevant for our economy, our society and the preservation of our environment. Solid and Fluid Mechanics are a core part of the educational programmes of a number of disciplines, e.g. Civil Engineering, Mechanical Engineering, Maritime Technology, Applied Physics, Aerospace Engineering, Applied Mathematics and Chemical Engineering.

8. Short description of sub programmes related to research school EM 8.1 Non-linear dynamics of mechanical systems

The numerical and experimental study of non-linear and in particular non-smooth mechanical systems, such as systems with friction, impacts or other constraints are key activities in this sub-theme, and play an essential role in the modeling and analysis of advanced mechanical systems. The research on these phenomena is highly relevant in many engineering applications (friction in high-performance/high-precision systems, drill strings, high-speed milling, hybrid control systems etc.). Numerical aspects are notably difficult, but are becoming more and more feasible with increasing computer power.

8.2 (Structural) acoustics and noise control, optimization This sub-theme deals with various structural vibrations and the associated sound radiation. The focus is on the one hand on numerical/computational tools for acoustic models, and on the other hand on the experimental validation of those tools. Subsequently, both passive and active means for acoustic noise suppression are investigated. Several mechanical applications are used as benchmark examples, particularly tyre–road noise. The development of tools for optimization is essential in the dynamic behavior of mechanical constructions. Much of the research centers around near field acoustic holography. In this context, the TU/e start-up company SORAMA as a spin off from the Dynamics and control group is mentioned. Related to research theme “structural Dynamics and Control”

8.3 Vehicle dynamics, tire dynamics and control Vehicle Energy Management Systems Topology Design Research is done on energy management of the complete power train, including the design trade-offs for hybrid vehicles with an internal combustion engine and an electromotor. Advanced model-based optimisation methods, like dynamic programming, are used for the off-line generation of optimal trajectories for the variables that dictate the energy supply from the combustion engine and/or the electromotor. We started a new research project on a hybrid truck. Vehicle Dynamics and Tyres Since 2002, the group has been responsible for the research and teaching in vehicle dynamics. The research focuses on modeling, analysis and control of articulated vehicles, and modeling and analysis of vehicle tires. For the latter, extensive use is made of the flat plank tyre tester. The tyre research is linked to the tyre–road noise research referred to above. Related to research theme “structural Dynamics and Control”

8.4 Mechanical Design and Vision The mechanical design group Construction and Mechanism is jointly headed with Prof.Dr.Ir. M. Steinbuch (Control Systems Technology). Dr.ir. P.C.J.N. Rosielle leads the activities in the C&M lab., which at the moment comprises 7-8 PhD students and about 10 MSc students. Focal point in the lab is the Construction and Design of Advanced, Novel Mechanical Systems.

31

A separate activity mostly iniated by prof.dr.ir. P.P. Jonker (part-time professor at the TU/e, main workplace TUD) deals with Vision in advanced mechatronic systems. Two PhD students and a number of MSc students work in this field. Related to research theme “structural Dynamics and Control”

8.5 Systems Design Optimization Optimization methods to support systematic design and improvement of complex engineering systems are investigated. We concentrate on simulation-based design optimization in the context of manufacturing system and distribution center networks, manufacturing machines, automotive systems, and micro-mechanical systems. Optimization methods and tools are being developed that can deal with typical governing characteristics such as: one or more computationally expensive computer simulation models in the loop, a mix of continuous and discrete design variables, stochastic design variables and responses, and dynamic response behaviour. The development of techniques for approximation, meta-modelling, and lumped-parameter modelling that can be utilized in the optimization plays a central role in our research work. Furthermore, methods for design optimization of multidisciplinary and multi-level decomposed systems have our special interest. Related to research theme “Reliability and Optimization”.

8.6 Control of Manufacturing Systems In this sub programme two main streams can be considered. The first stream considers a class of manufacturing systems that can be approximately modelled by means of a continuous time fluid or flow model. For this approximate model, standard techniques from control theory can often be used to design controllers. As the manufacturing system has a discrete-event nature, a connection between the discrete event plant and the continuous time controller has to be developed. Continuous time signals have to be converted to discrete-events and measurements of discrete states need to be filtered for a better control performance. Currently available flow models often ignore variability, whereas queuing theory often considers only steady state behaviour. For that purpose new (mathematical) models need to be developed that include both variability and dynamics. It is clear that preferably these models should be suited for applying standard control theory in order to control these systems. The second stream considers the control of a network of servers through which many types of jobs flow, where it is assumed that servers require a setup time when switching between types. Such networks can be used to model complex communication, traffic or manufacturing systems. Related to research theme “structural Dynamics and Control”

8.7 Nonlinear and hybrid dynamics

In this subprogram two main directions can be considered. First, general questions of nonlinear dynamics and control of mechanical systems including switched (hybrid) systems are studied. In recent years hybrid systems attracted a considerable attention due to possible applications in various fields of science and technology. The theory of hybrid systems is far from its completeness. Therefore it is of interest to further develop methods of analysis and design for such systems.

32

In this research particular attention is drawn to the following two questions: analysis of oscillations in hybrid systems and formalization of some mathematical models of hybrid systems using the formal languages approach. The formal language used is Chi developed in the Systems Engineering group. The second direction of the research is to study applications for the theoretical results in the framework of systems engineering. Nowadays complex manufacturing machines contain discrete-event and continuous-time parts with interactions between the components. These interactions can result in nonlinear dynamical phenomena that should be taken into account during design and real-time control of the machine. This research theme has a strong relation with the topic Embedded Systems (within the Institute for Programming and Algorithmic) Related to research theme “structural Dynamics and Control”

8. Short description of sub programmes related to research school EM 8.1 Systems Design Optimization

Optimization methods to support systematic design and improvement of complex engineering systems are investigated. We focus on the development of simulation-based optimization methods for manufacturing systems, mechanical systems and product design. The development of techniques for approximation, meta-modelling, aggregation, and lumped-parameter modelling that can be utilized in the optimization plays a central role in our research work. Furthermore, methods for design optimization and multi-level decomposed systems have our interest.

8.2 Control of Manufacturing Systems In this subprogram two main streams can be considered. The first stream considers a class of manufacturing systems that can be approximately modelled by means of a continuous time fluid or flow model. For this approximate model, standard techniques from control theory can often be used to design controllers. As the manufacturing system has a discrete-event nature, a connection between the discrete event plant and the continuous time controller has to be developed. Continuous time signals have to be converted to discrete-events and measurements of discrete states need to be filtered for a better control performance. Currently available flow models often ignore variability, whereas queuing theory often considers only steady state behaviour. For that purpose new (mathematical) models need to be developed that include both variability and dynamics. It is clear that preferably these models should be suited for applying standard control theory in order to control these systems. The second stream considers the control of a network of servers through which many types of jobs flow, where it is assumed that servers require a setup time when switching between types. Such networks can be used to model complex communication, traffic or manufacturing systems.

8. Short description of subprogrammes related to research school EM 8.1 Multi-scale Mechanics & Structure-Property Modelling

This research topic focuses on the mechanical behaviour of solids, with particular emphasis on (1) multi-scale aspects; (2) micromechanical aspects, involving a major influence of the microstructural morphology. The thorough understanding and modelling of small scale processes that can be identified in the complex evolving microstructure or interface is thereby a key issue. The research topic concentrates on various fundamental aspects governing the deformation and integrity of materials across the length scales, with a particular emphasis on mechanical properties.Typical topics addressed are single- and poly-crystalline structures, dislocation networks in metals, structured single crystal alloys (turbine blades), structured ceramics, complex structured polymer-metal geometries (flexible displays), (semi-) crystalline polymers with various inclusions, and fibrous materials such as paper(board). The ultimate goal is to arrive at multi-scale solution schemes and physically based constitutive descriptions which can be numerically implemented, enabling an accurate analysis of engineering products or product manufacturing processes.

8.2 Microscopic Aspects of Deformation

This research topic aims to provide a sound experimental basis for the computational efforts in the group, through a range of specific set-ups spanning a hierarchy of interacting length scales. Research topics are mainly concerned with the analysis of microscopic aspects of deformation and adhesion at interfaces (e.g. polymer-metal interfaces), of multi-phase materials (e.g. micro-electronics solders), multi-layered structures (e.g. flexible displays), microsystems etc.

8.3 Micromechanics of Functional Devices

This research topic focuses on the micromechanics of devices on miniaturization. In miniaturized products, materials cannot be trivially considered as continua. Furthermore, boundary, surface and interface effects play a dominant role. Changes in deformation mechanisms and failure processes directly influence the lifetime of functional devices. Both numerical and experimental tools and techniques are being developed for the analysis of these phenomena and their influence on the performance of microsystems.

8.4 Damage, Fracture and Reliability

This research topic focuses on mechanical failure as an important design criterion for products and components. Both prevention and control of damage are thereby relevant. The correct

47

prediction of this ultimate behaviour presents many challenges of both a numerical and an experimental nature. Non-standard continuum theories are required to deal with intense localization phenomena. The transition to discrete failure and the coupling with the underlying microstructure in a multi-scale setting is another goal pursued here.

8.5 Manufacturing and Injury Biomechanics

This partly more application-oriented research topic constitutes the group’s link with the Manufacturing and Automotive Engineering Science activities at the TU/e. In the past period, it has focused mainly on optimal forming processes and passive safety research for automotive applications, i.e. prevention of injuries caused by accidents. The focus for the coming period is the development and use of high-performance materials in manufacturing and automotive applications and multi-scale injury mechanics.

8.6 Micro- and Nano- scale engineering

• Design of a 3D vibrating microprobe Limitations of existing measuring probes for coordinate measuring machines (CMM’s) include their relatively high contact forces and their inability to measure features smaller than 50 micrometer. In order to deal with these limitations, a new type of 3D measuring probe is under development. This new probe does not employ a static measurement principle, but uses changes in its dynamic properties to determine contact. This is realized by exciting the probe at its natural frequency, as the probe makes contact with a surface the dynamic properties of the system will change, i.e. the vibration of the probe changes. This change in vibration is then used to determine contact and the direction in which the contact is made.

8.7 Free-Boundary & Interface Problems

Many problems in science and engineering are characterized by a connection between disparate subsystems at a common boundary or, similarly, by a fundamental change in the behavior of a single system across an infinitesimally thin layer. Typical examples are dynamic and thermodynamic interactions between a fluid and a solid, the interaction between two distinct immiscible fluids, or the intrusion of a tumor into healthy tissue. Generally, the interface between the subdomains constitutes a free-boundary, i.e., it is not fixed, but its motion is interconnected with the (initial-)boundary-value problems on the adjacent subdomains. Interface and free-boundary problems pose fundamental challenges to numerical simulation methods, on account of the resolution requirements at the interface and/or the complicated interdependence between the boundary-value problems and their domain of definition. A central theme in the research of the MEFD group is the development and analysis of advanced numerical techniques for interface and free-boundary problems.

8.8 Computational Fluid-Structure Interaction

A particularly important class of interface problems is fluid-structure interaction. In accordance with the reductionistic approach that pervades modern science, the fields of fluid and solid mechanics have historically developed independently. In fluid-structure interaction, a proper understanding of both subsystems is required. In addition, the interface between the fluid and the structure introduces additional complications, on account of its free-boundary character and the nontrivial interconnection between the fluid and structure subsystems via boundary conditions. The disparity between the fluid and structure subsystems moreover generally reflects in a wide range of length and time scales in the aggregated problem. An important focal

48

point of the group pertains to the development and analysis of efficient iterative solution techniques and advanced finite-element discretization methods for strongly-coupled large-displacement fluid-structure-interaction problems.

8.9 Swelling mechanics

The mechanics of swelling materials comprises applications in the geotechnical as well as the biomedical areas. Clays, shales, intervertebral disc, cartilage, hydrogels and living cells are a few examples. Mechanical deformations are inevitably coupled to fluid and ion diffusion-convection and to electrical potential gradients and current in the media. Crack progagation and mechano-transduction are important themes of research.

understanding how small-scale (microscopic) information affects the behaviour at larger (meso and macroscopic) scales. The activities focus on the development of robust and accurate computational models that follow the physics of the problem closely, and obey rigorous mathematical principles characterizing the separate scales and their coupling.

8.2 Multi-physics modelling of structures and materials:

Modelling processes characterized by the interactive phenomena originating from multiple physical processes, such as thermo-mechanical processes that define the failure response of metals under varying temperatures, or thermal-chemical-mechanical processes that define the fracture behaviour of brittle coating systems under thermal oxidation.

8. Short description of subprogrammes related to research school EM

8.1 Scientific Computing The main emphasis in this programme is on analysis and numerical simulation of problems arising in technology. Research is often induced by specific applications, yet being seen as part of a larger area where mathematical tools and in particular numerical methods can be applied. Hence both fundamental (numerical) research and applying the results to specific applications are typical for Scientific Computing. The following areas specify the actual research:

8.1.1 Glass Morphology Analysis and simulation of the glass flow in (partially) confined areas, such as in mould for producing jars and bottles. Flows in a glass tank (oven). Investigating the heat transport by various phenomena, like diffusion and convection. Co-operation in this research is with TNO-TPD ceramics and glass. The research is embedded in an EU project “MAGICAL” Furthermore there exists cooperation with the departments of Mechanical Engineering and Chemistry (TU/e). Related to research themes “Computational Mechanics” and “Mechanics of Materials”.

8.1.2 Ordinary Differential Equations and DAE

Problems that exhibit an evolutionary character will result in ODE after spatial discretisation. Moreover problems in control and mechanics often lead to such equations more directly. Quite often they are coupled with some (algebraic) constraint equations, resulting in DAE. Matters like stability and accuracy of numerical methods still provide for important questions. Co-operation exists with the TU/e-department of Mechanical Engineering. Related to research theme “Computational Mechanics”.

8.1.3 Large Scale System Solving

In solving partial differential equations numerically, one encounters complex larger (non) linear systems which exhibit a sparsity structure. In order to be able to solve them one need special

66

iterative solvers, like multigrid. In this area one can also often employ parallel architectures fruitfully. Co-operation exists with TNO-TPD and the TU/e-department of Computer Science. Related to research theme “Computational Mechanics”.

8.1.4 Modelling and Finite Element Applications

Although there exists a variety of FEM packages, it is often necessary to tailor methods for specific problems. Further development and improving them is a core activity. A particular aspect is the visualisation, which is increasingly important due to the ever increasing complexity of problems to be solved. Related to research theme “Computational Mechanics”.

8.1.5 Boundary Element Methods and Approximation

The research on BEM is concentrating on the quality of approximations of non-homogeneous problems. In particular it is investigated how various basic approximation methods like radial basis functions lead to convergence and therefore efficient methods. Related to research theme “Computational Mechanics”.

8.1.6 Wave Analysis for lithography Analysis of diffraction gratings that are used to determine the position of a wafer in a waferstepper. Numerical methods like RCWA (Rigorous Coupled-Wave Analysis) are investigated to solve these equations in a stable and accurate way. New software tools will be developed for sensors that have the improved RCWA algorithm incorporated.

Related to research theme “Computational Mechanics”. 8.1 Applied Analysis

The main emphasis in this programme is on mathematical analysis of technological problems. Research is often fostered by specific applications, after which it may trigger more fundamental, and thus more generally applicable research:

8.2.1 Mathematical Methods in Continuum Physics • Slow viscous flow of polymeric melts: considered is the mathematical simulation of

manufacturing processes for polymers such as fiber spinning, extrusion and injection moulding. These processes are considered as slow viscous (Stokes-) flows. The polymeric melts are described as nonlinear thermoviscoelastic fluids. Analytical and numerical evaluation of the resulting system of partial differential equations is looked for.

• Modelling of direct imaging processing in photocopiers: Description of the toner particles between drum and dip roller, including collision, friction, and electromagnetic forces. Modelling of the toner as a granular medium or as a conglomerate of many rigid particles. Numerical simulation on basis of discrete element analysis.

• Analysis of dislocation structures in crystal lattices: Dislocations are the carriers of microscopic plastic deformation. In this project we develop rigorous mathematical methods for the upscaling of a large number of such dislocations, with the aim of constructing a rigorous derivation of mesoscopic crystal-plasticity models.

8.2.2 Fundamental Analysis of (Non-Linear) Evolution Problems Our research in functional analysis is concentrated on evolution equations. An inspiring source of inspiration are non-linear evolution equations arising from free boundary value problems in quasi-stationary fluid dynamics (Stokes flow, Hele-Shaw flow, polymer flow).

8.2.3 Mathematical Methods for Impacting Oscillators In this subprogramme the dynamics of oscillating systems with impacts is studied. These systems

show universal bifurcation behaviour, such as ‘period-adding’ bifurcations. Applications of the

67

theory are found in atomic force microscopy, an experimental method to scan the detailed structure of surfaces from interactions between the surface and an oscillating problem.

8.2.4 Stability of thin-walled structures A variational criterion for the hurt of stability of thin-walled shell structures provides a new lower

bound for the loading capacity. We are investigating the implications of this criterion for the classical case of an axially loaded cylinder.

8.2.5 Industrial Mathematics

Problems and questions from industry. All subprogrammes within 7.2 are related to research theme “Mechanics of Materials”.

8. Short description of subprogrammes related to research school EM 8.1 Structural Tailoring, and Design and Optimization

The demands of high-performance, structural integrity, durability, low weight, and minimum cost pose an important challenge to structural designers. New materials may assist in satisfying some of these demands, but at the same time give rise to significant new problems for the designers. Furthermore the structural design can no longer be seen as an isolated activity, but must play its part in a multi-disciplinary approach to the design of the aircraft or spacecraft as a whole. The traditional approach to design is no longer adequate unless it can be supplemented by a numerical, computer-based approach in which the trade-off between conflicting design requirements can be quantified, and many more alternatives evaluated. Optimization plays an important role in this process, by providing a tool to identify the active design constraints and to steer the design towards some required goal such as minimum weight or cost. The goal of the research efforts in this area is the development of efficient and robust design and optimization tools for a variety of challenging structural design problems, which meet the needs that industry is facing. The subprogram includes the following topics: • Development of design and optimization procedures for specific structural design problems; • Theoretical optimization including multi-level procedures and optimization of structural

shape and layout; • Tailoring of advanced fiber-reinforced composite structures; • Design and optimization of actively sensed and actuated structures.

8.2 Stability and Vibrations of thin-walled structures In modern designs, which are often obtained by use of one of the structural optimization codes and which may be of new high strength materials such as advanced composites, structural response is often dictated by the stability and vibration behavior. This is due to the drive for achieving lightweight structures which result in thin-walled constructions. Such structures are sensitive to imperfections and display nonlinear response characteristics. This implies the need to investigate and understand the response characteristics of thin-walled structures under different loading conditions by carrying out extensive numerical calculation and/or experimental verification. A key issue is the development of fast and accurate analysis capabilities for thin-walled structures, incorporating all the theoretical knowledge accumulated in the last decades through intensive research in the aerospace, nuclear, and offshore fields, and making efficient use of the currently available interactive and (super-) computing facilities. Part of the ongoing thin-walled structures research is therefore concerned with the buckling, post-buckling, vibration and dynamic stability behavior of shells. The goal of the research efforts in this area is the availability of improved design criteria and the necessary analysis tools. The subprogram includes the following topics: • Theoretical, numerical, and experimental studies of the collapse behavior and nonlinear

vibration behavior of imperfect composite shells under static and dynamic loading; • Development of an International Imperfection Data Bank and DISDECO (Delft Interactive

Shell DEsign COde); • Development of efficient semi-analytical and Finite Element based tools (reduced-basis

methods) for the nonlinear analysis of slender and thin-walled composite structures. 8.3 Advanced Computational Methods

A wide variety of challenging problems in aerospace engineering cannot be satisfactorily solved using the traditional finite element method based on Lagrange polynomials. Limitations of the traditional FEM are related to its high computational cost in complex systems and/or its inability to model relevant features in the problems. The sub-program “Advanced Computational Methods” focuses on the development of novel computational methodologies intended to address the shortcomings of the traditional FEM. One main thrust in this program pertains to the area of Isogeometric Analysis, which provides a seamless connection between objects created in CAD software and the corresponding analysis. This computational approach streamlines the design process and supports the activities in other research sub-programs. A second focus point is the development of computationally-efficient Multiscale Analysis algorithms that relate the microscopic behavior of materials and systems to their effective (macroscopic) response. Both concurrent and hierarchical multiscale approaches are used for advanced material modelling and solution of coupled problems. The subprogram includes the following topics: • Isogeometric analysis and design of composite turbine blades and shells • Isogeometric analysis of fluid-structure problems • Multiscale simulations of multiphase steels • Lifetime predictions of self-healing thermal barrier coatings used in aeroengines

8.4 Mechanics of lightweight composite materials Increased use of composite materials in aerospace, automobile, shipping, and civil engineering structures has revealed several areas where improved understanding of the performance of these structures under mechanical loading is required in order to decrease their weight further or tune their performance more accurately to specific requirements. Relevant requirements are frequency response, crash absorption capability, and geometric stability under thermomechanical loads. More recently, damage tolerance has emerged as one area where improved modeling techniques combined with accurate testing can lead to more efficient designs. The complexities of damage types (matrix cracks, delaminations, fiber breakage, fiber matrix disbands) and their interaction under mechanical loading suggest the need for detailed modeling at the ply or even the matrix/fiber level in order to accurately capture the behavior and predict damage creation and evolution. In addition, the reduction of strength and stiffness of composite structures under cyclic loading requires analytical models that evolve with cycles and simulate accurately the creation of different types of damage and their interaction. The following topics are included in this sub-program: • Damage creation during impact of composite structures • Residual strength of composite structures after impact • Structural response of grid-stiffened composite structures • Analysis of the effect of delaminations in composite structures • Determination of cycles to failure under constant amplitude and spectrum loading • Improved crash absorption of composite structures

8. Short description of subprogrammes related to research school EM 8.1 Structural Optimization and Mechanics

Analytical modelling is only possible for a very limited number of structures or parts of structures. With the development of high-performance computer facilities, however, an increasing number of mechanical problems can be modelled and analysed numerically. The finite element method is the method that is often made use of in these cases. Analysis on the basis of numerical techniques is complicated by nonlinearities, caused by material behaviour, geometric effects, contact and/or friction. Moreover, multidisciplinary interaction may be important. This is especially the case for Micro-Electrical-Mechanical Systems (MEMS) and high-tech applications. Because of these aspects, the analysis of practical problems takes a tremendous effort. Therefore, further development of efficient, multidisciplinary numerical modelling techniques is required. These techniques should be tailored for high-performance computer architectures. The aim is to develop such techniques using approaches that strengthen and exploit the fundamentals of engineering mechanics. Once numerical techniques are incorporated in a design process, for which often many intermediate designs and corresponding design sensitivities must be evaluated, the efficiency requirements are even more demanding. This holds for a design process in which intermediate designs are evaluated "manually", but becomes more important for (partially) automated optimization processes. Improvement of structural optimization techniques cannot be achieved independently from new developments in Computational Mechanics. Only a close integration of structural optimization techniques and numerical analysis strategies can yield the most efficient design tools. Clearly, manufacturing constraints impose additional challenges on the optimization.

91

Within this theme, the fundamentals for modelling, analysis, design sensitivities and optimization of structures will be developed. The focus will be on the multidisciplinary links between these aspects. Furthermore, new developments will be translated in prototype designs, ready for laboratory testing and ultimately made available for day-to-day practice. For this purpose we are collaborating with more application-oriented groups and companies.

8.3 Dynamic Behaviour of Mechanical Systems

Predicting and controlling the dynamical behavior of systems has become more important than ever before since new material and design techniques render structures lighter, more complex, more flexible and multi-functional. Thus predicting their dynamic performance with accuracy is crucial (e.g. response of constructions to surrounding perturbations, positioning of flexible manipulators, dynamic load analysis on machines,.). Also the advent of new materials such as piezoelectric ceramics and the development of novel mechanical structures such as Micro-Electro-Mechanical systems (MEMS) require modern dynamic analysis to take into account the coupling between different physical fields, treated separately in earlier days. Tackling multi-physical problems and analyzing fully coupled systems (thermal, acoustic, electric, fluid and structural for instance) is one of the essential challenges underlying the development of new analysis tools and innovative design approaches in mechanical dynamics. The objective of the research work in the Engineering Dynamics group is on one hand to develop numerical tools that allow analysis of complex systems, and on the other hand to improve the understanding of dynamical behavior (e.g. vibration analysis and measurement, stability prediction). The research is centered on the development of novel numerical methods and advanced algorithms for efficient computing and testing. Specifically, the section is centering its reseach around the fields of expertise

• Multibody Dynamics, • Numerical methods for dynamics, • Multiphysical modeling • Experimental Dynamics

and application fields usually considered are bio-medical, automotive, aerospace and aeronautics and Microsystems.

8.4 Reliability of Structures and Processing Even the most sophisticated analysis and design procedures traditionally use a deterministic approach, often based on (arbitrary) safety factors. A new dimension is introduced by taking into account the variability in material properties, geometry and operation conditions and to quantify it by means of probabilistic descriptions. The recent ability to operate inexpensive PCs in a parallel network and the development of specific algorithms for computational stochastic methods in a mutiscale context, often with the added complication of non-linearities and multiphysics, have brought within reach a systematic incorporation of the probabilistic aspects in the modelling of engineering materials and systems. A direct consequence of this is the possibility of predicting the reliability of an object or system with respect to a performance requirement in a rational fashion. These advances also have relevance for many problems in processing, where a proper modelling of manufacturing introduced defects is a conditio sine qua non for a proper design of a system. Related to the research theme “Reliability and Optimization”.

8. Short description of sub programmes related to research school EM 8.1 Structural Dynamics and Acoustics (Prof.dr.ir. A. de Boer)

The research in this discipline is directed towards: · Fluid-structure interaction and acoustics, with emphasis on thermal viscous wave

propagation and acousto-elastic coupling and the accompanying noise production. · Structural dynamics, involving rotating components in machinery and optimisation and

actuation of vibrating structures. · Dynamics Based Maintenance The research of the group aims at generation of new, fundamental knowledge by combining numerical and experimental techniques. Based on this knowledge engineering tools are validated and made ready for application in key industrial problems. A characteristic feature of all themes is the innovative use of advanced numerical simulation methods in a design environment. Crucial information that is difficult or even impossible to obtain from experiments is added through numerical models. Current topics are:

Structural Dynamics (1) Optimization of Dynamic Systems with emphasis on model reduction methods.

Optimization problems concerning complex structures with many design variables may entail an unacceptable computational cost. This problem can be reduced considerably with a multi-level approach; a structure consisting of several components is optimized as a whole (global) as well as on component level. Knowledge in this field has been developed within the PhD project of Didem Akçay Perdahcioğlu and now the gained knowledge is used for the optimization of thermoplastic structures in the framework of the Dutch TAPAS (Thermoplastic Affordable Primary Aircraft Structure) programme. The research of the UT part within TAPAS has been finished in 2012 by post-doc Semih Perdahcioğlu. Another spin off of the PhD project of Didem Akçay Perdahcioğlu is the participation in the European project GLfem (Generic Linking of finite element models) . The contribution of the UT is to investigate methods to couple reduced dynamic models with nonmatching interfaces. This work was carried out by Didem Akçay Perdahcioğlu and has been finished in 2012.

(2) Rotor Dynamics Rotating parts in machinery are sources of vibrations and can therefore affect the life time of the rotating part itself and the whole machine drastically. The tendency to optimize the functional performance of structures results in modern designs which often exhibit a

110

minimal weight and very tight safety factors. For high speed rotating (micro) systems ball bearings are no longer feasible and air foil bearings are a good alternative. Research is going on to identify the dynamic properties of this kind of bearings and to derive design and production rules. In 2010 a postdoc did research on this subject and in 2012 this research has been finished by Marieke Bezemer.

Fluid-structure interaction (FSI) and acoustics (1) Viscothermal wave propagation

(2) Sound-absorbing materials.

A closely related part of the FSI research program, involves the development of methods and models concerning sound-absorbing materials. This research is carried out by Erwin Kuipers. He will defend his thesis on September the 4th 2013. Another research topic is on diffraction of sound due to tyre-road noise. The latter has been awarded with an STW valorization grant and in 2012 the spinoff company 4Silnce have been founded. This company commercializes this method in close collaboration with the Applied Mechanics group. Active methods to reduce and absorb sound are investigated together with TNO by Derek Land.

(3) Efficient analysis and measuring methods for source localisation

(4) Thermo-acoustic structural interaction During combustion in a gasturbine noise is generated which can interact with the gasturbine wall. Due to this interaction undesirable acoustic pressure fields can be generated that disturb the flame. The latter can affect the efficiency of the combustion process. The objective of this study is to investigate the interaction between the gasturbine structure and the thermo-acoustic pressure generated in the combustion chamber. This study is carried out in close collaboration with the Thermal Mechanics group of the University of Twente. In the framework of the (Marie Curie) Limousine project in 2012 numerical methods (developed in 2011) have been applied on real life gas turbines to predict fatigue and damage in the liner structure. This research is carried out by Can Altunlu. He will defend his thesis on July the 12th 2013. Together with the Thermal Mechanics group of the University of Twente research is carried out on Thermo-acoustic heat pumps. In 2012 a start has been made with the development of numerical models which these pumps can be simulated. Further a demonstrator has been build. This is the topic of PhD student Anne de Jong.

(5) Tyre/road noise Traffic road noise is a serious environmental problem and effective countermeasures are needed to reduce noise. The main components of the radiated noise are engine noise and tyre/road noise, where engine noise dominates at low speeds. Road noise is generated through the interaction between a rolling tyre of a vehicle and the road surface. Many different mechanisms contribute to the generation of tyre/road noise. Because most generation mechanisms originate from the contact region, modelling of the interaction between tyre tread and road surface is crucial for an accurate prediction of tyre/road noise. An analysis procedure has been developed such that the radiated tyre noise can be calculated. In 2012 a new project in this field has been started which focus on the

111

incorporation of tyre treads and bahavior of the pavement. The work of Lambert Russcher has been taken over by Marieke Bezemer.

Dynamics Based Maintenance

In 2012 Dynamics Based Maintenance is the new chair on which prof.dr.ir. Tiedo Tinga has been appointed. He is responsible for the projects mentioned below.

(1) Structural Health Monitoring (SHM) This project is in collaboration with Production Technology, Prof.dr.ir. R. Akkerman. See chapter 13 ‘Production Technology’ for more details. Ted Ooijevaar is PhD student on this subject. A new European project, called WIBRATE has been started together with the wireless network group at the university of Twente with the objective to perform SHM with wireless systems. Andrea Sanches Ramirez is PhD on this project.

(2) TTIW Wetsus Distribution. The research program of the Technological Top Institute Water, financed by the Dutch government and Dutch industry, focus on Ultrasonic measuring technologies (see InnoWator project) to measure the dynamic response of a water pipe during service. The relation between the dynamic response, the age of the material and the resulting remaining life time estimation are subject of the Wetsus theme program Distribution. Mahmoud Ravanan has decided to stop on this project as PhD student. It will be taken over by a post-doc in 2013.

(3) InnoWator This project is in collaboration with Production Technology, Prof.dr.ir. R. Akkerman. See chapter 13 ‘Production Technology’ for more details.

(4) Rotor Blade Dynamics Green Rotor Craft (GRC) is one of the research projects whitin the European funded Joint Technology Initiative research program “Clean Sky”. The objective of the GRC project is to reduce the environmental impact of helicopters. A smart use of resources, in terms of vibrations of the rotary system, and an optimisation of the rotor blade performance are set as the main research activities. Two PhD’s are involved in this project. Pieter de Jong on power harvesting and Alexandre Paternoster on the design of an active mechanism for a gurney flap on a scaled rotor blade. Both will defence their theses on February the 28th. position are defined in this project.

8.2 Nonlinear Solid Mechanics (Prof.dr.ir. A.H. van den Boogaard)

The mission of the Chair Nonlinear Solid Mechanics (NSM) is to develop and experimentally validate advanced numerical methods for the accurate simulation of non-linear mechanical behaviour, in order to support the industrial needs for optimal and efficient methods for designing and manufacturing of parts and products. The main application areas of the chair are • Material Forming Processes • Mechanical behaviour of biological tissues Increased demands for accurate and computationally efficient simulations require that a number of topics have to be addressed:

• Improved macroscopic models for describing material behaviour. Accurate constitutive equations are required in order to predict the final shape of a work piece after forming and subsequent “spring back” and its subsequent service properties. In particular the effect of the initial and evolving anisotropy, the changes in loading path as present in multi-stage forming processes, the strain rate dependency, the consequences of

112

temperature changes in warm forming processes and the effects of annealing periods between successive forming steps have to be properly accounted for, including the effects of phase transformations. Nonlinear material behaviour in biological materials is related to large visco-elastic deformations in fibrous materials or to fracture phenomena of hard materials like bone. Both types of materials show significant anisotropy. Material properties are commonly determined from uni-axial tensile experiments, but the deformation mode in forming is usually 3-dimensional and non-proportional. Therefore, constitutive models need to be able to consider arbitrary 3D loading paths. Although macroscopic models are required for full-process simulations (regarding CPU-time), development of the models benefits from considering micro-structural evolution and therefore microscopic models are also investigated. In order to validate material models under multiaxial stress state and arbitrary deformation paths, a biaxial test facilty is available. The test facility allows for biaxial loading under simultaneous bi-directional shear and tension/compression of sheet material, including strain path changes and strain rate changes.

• Advanced solution algorithms for forming processes Forming processes are mainly simulated with the finite element method. Although the method is successful for a wide range of applications, severe problems occur when finite elements are getting distorted. Meshless methods potentially avoid this problem. A project on the applicability of meshless methods for forming process simulations has been running recently. A local-maximum-entropy method was applied that degenerates to a Smoothed FEM approach with nodal integration. The nodal connectivity is evaluated per time step such that it is optimal for that time step. In this way, forming processes could be simulated with a Lagrangian analysis that would lead to elements being turned inside-out in an ordinary FEM simulation. Another focus for the sub-programme ‘solution algorithms’ is the reduction of calculation time. Two projects currently focus on processes were a ring is deformed locally, but the deformation zone is moving repeatedly over the complete ring during the process. In a straightforward analysis approach calculation times would be extremely high and flexible remeshing or ALE techniques are used to make these calculations more manageable.

• Joining, surfaces, contact and friction Similar as for material modelling, also the surface behaviour must be simulated with high accuracy. This field considers bonding and friction in relation to surface pressure, relative velocities, roughness, temperature et cetera. A project jointly with the Surface Technology group aims to provide a friction model that describes the effects of the surface topology on the micro scale in FE simulations on the macro scale. The algorithm incorporating the model must be applicable to full-scale automotive sheet metal forming simulations. Another project is aimed at the development of an innovative modified tool for the Friction Stir Welding (FSW) process. Contrary to regular FSW, filler material is supplied to the weld area during welding through an adapted FSW tool. This is a joint project with the Production Technology group.

113

• Optimization When processes can be modelled accurately enough, the logical next step is to optimize processes by automatic numerical optimization. A project on optimization-under-uncertainty started at the end of 2009. The project focuses on the calculation and optimization of robustness in metal forming processes. If robustness is not considered in optimization of forming processes, the resulting optimum is usually critical with respect to constraints. Arbitrary safety margins may be either insufficient or not fully exploit the full potential of the material; therefore the optimization model should include variability in the material properties, tool geometries and process conditions. The goal is to develop a methodology for the prediction of the mean and standard deviation in sheet metal forming as obtained on the shop floor by Statistical Process Control and to optimize a process while reaching a required robustness. In 2011 a related European project (MEGaFiT) started, in which adaptive control of the tooling is introduced. This further complicates the prediction of success rates.

8. Short description of sub programmes related to research school EM

The subject of research of the surface technology and tribology group is the interaction between surfaces. The nature of the interaction between the opposing surfaces depends on the operational conditions and therefore the physics describing the interaction is for each situation different. In the figure the interaction between surfaces is in general depicted. The system studied is represented by envelope I, envelope II is subject within the courses given by the surface technology and tribology group.

Based on validated models design “tools” are developed for reliable and accurate prediction of friction and wear. The main subjects are I) High Tech Systems and Energy, II) Health and III) Reliability and Durability.

8.1 High Tech Systems and Energy The theme high tech systems deals with the realization of contacts in mechanical systems operating in extreme environments. Examples are low temperature, high temperature as well as low pressure (e.g. vacuum systems) and high pressure environments. Although these contact may appear very different, there are also many similarities. In order to realize such contacts, ceramics, polymers, dedicated coatings and surface treatments are required instead of metallic surfaces lubricated with (mineral) lubricants. If contacts are lubricated, typically solid lubricants are used. Further, in all cases, the environment is significantly influencing the tribological behaviour. The research is performed by a combination of model development and experiments in these extreme environments. Examples, of topics studied in the theme are solid lubrication at high temperatures, bonding in composites and positioning in vacuum systems. A big societal theme which gets a lot of attention nowadays is to make energy available in a sustainable way using sources like wind and sun. However, an efficient use of the available energy does not receive the necessary attention. Within this theme we focus on the reduction of energy loss. This loss can be the result of frictional losses and/or the waste of components (materials) in mechanical systems. The systems studied are mainly liquid lubricated systems which can be for instance found in the transport industry (automotive and railway) and metal forming industry.

8.2 Health The growth of engineering activities for health care, sports and medical applications has initiated the development of innovative simulation and visualization techniques. This area of industry is e.g. searching for tools that can predict the human perception of products as a function of design optimization parameters. Such tools would also reduce the need for extensive panel testing or for animal testing. Friction and wear in human – product interfaces is considered to be of high importance for such an approach. Successful research requires knowledge on tribology, surface engineering, materials technology, physiology and dermatology, with a clear focus on industrial design. Research on the tribology needed for innovation in engineering of human - product interactions is structured in this theme by combined PhD projects focused on : 1) Skin Friction Fundamentals; 2) Sensing & Control of Friction; and 3 ) Bio Inspired Interfaces. Skin tribology requires in vivo, subject and anatomical location specific test methods, that are developed within research projects. Current predictive friction models can only partially be applied to predict in vivo skin friction. The reason for this is found in limited understanding of the contact mechanics at the asperity level of product - skin interactions. A recently developed model gives the building blocks for enhanced understanding of friction at the micro scale. Only largely simplified power law based equations are currently available as general engineering tools. Surface texturing and polymer brush coatings are promising directions as they provide way and means to tailor friction in sliding contacts without the need of major changes to the product.

125

8.3 Reliability and Durability

Within the theme durability and reliability the developed knowledge should lead to the prediction and/or extension of maintenance intervals. Initially, the research is directed towards the development of models for wear and lubrication. Physical models make it possible to predict the performance under conditions which cannot be tested, either because of unacceptable high costs, or because of unacceptable duration. Wear models predict the transition from mild to severe wear and wear rates as a function of the operating conditions. Applications are wheel-rail contact, camshaft follower contacts, gears, rolling bearings and plain bearings. The wear models combine the response of the material and lubricant on severe operating conditions. The lubrication models are developed to predict re-lubrication intervals. This work is primarily done for lubricating greases. Much work is done on understanding and modeling the rheology of grease and on the development of film thickness models for grease lubrication. The lubrication and wear models should be integrated into durability models which can be used to calculate the reliability or life-time of equipment. Special attention will be paid to so-called “early failures”, i.e. failures that do not fit into the failure distribution function corresponding to the expected failure mode. In the future, the interaction between the tribological phenomena in the various elements of a machine in combination with dynamic behaviour (varying operating conditions, start-stops etc.) on reliability and durability will be studied.

8. Short description of sub programmes related to research school EM

The research topics of the group Mechanical Automation related to the speciality of Engineering Mechanics can be summarised as:

8.1 Robotics and Micro Mechatronic Systems The dynamic behaviour of (industrial) manipulators and (micro) mechatronic systems is investigated. The focus is on mechanical systems and applications where the flexibility of parts or the complete system is relevant for the dynamic performance. Research topics cover: • The dynamic analysis and simulation of such systems in open and closed loop, i.e. with or

without a control system. • The design of these systems, which covers both the mechanical design as well as the

mechatronic design of the mechanical system and its control system. • The experimental identification and validation of these systems. The simulation and analysis of these mechanical systems rely strongly on the continuous development of the computer program “SPACAR”. It is based on a non-linear finite element method to analyse and simulate the kinematics and dynamics of mechanisms and manipulators or, more generally, multibody systems with non-linear behaviour due to large displacements and rotations. In this approach mechanisms may be composed of both rigid and flexible components. Locally linearised models can be derived to study e.g. natural frequencies and vibration modes. For control system synthesis and analysis input-output relations can be obtained for typical inputs and outputs of the mechanical system. The low-dimensional models that are obtained appear to be particularly suited to obtain prototype models of the mechanical part of a mechatronic system. For control synthesis of such systems it is essential to make use of these prototype models with a few degrees of freedom that nevertheless capture the relevant three-dimensional system dynamics. In the MOV-ET project manipulator concepts are investigated to realise high precision motion in vacuum. Our contribution to this project focuses on the use of elastic (or compliant) manipulators. These offer the advantages of motion with low friction and no backlash. In the models of these system we distinguish the links and the joints. The elastic joints should allow a rather large stroke, in which case they will exhibit non-linear behaviour. In particular the support stiffness decreases significantly which causes a deterioration of the system’s performance. With numerically efficient SPACAR models existing elastic joint designs have been optimised. With the gained insight a new joint concept has been conceived that offers high supporting stiffness especially for a large stroke. The final contribution in this project aims at combining the non-linear behaviour of the elastic joints with the finite stiffness of the links into a model of a complete manipulator. So-called super elements and model order reduction are being investigated. The project is planned to be completed with a PhD defence in 2013.

8.2 Vibration isolation control

The research on this theme within the graduate school on Engineering Mechanics has been concluded in 2010 with the defence of a PhD thesis.

8. Short description of subprogrammes related to research school EM Research in the Production Technology group addresses the technical issues of new products and new processes. The group focuses on the optimisation of both the manufacturing process and the product performance. ‘Processing’ and ‘Product performance’ of lightweight materials in structural applications characterise the main research themes of the Production Technology group. In our view processing and performance can be optimised after thorough analysis and modelling in combination with a firm experimental programme. The experiments identify the operating mechanisms, establish relevant material property data for the modelling and provide data to test the accuracy of the models proposed. An integral approach is pursued, taking into account the interrelations between the geometric design, the production process and the material properties. In the year 2012, the research on the subprogramme on Automated Composites Manufacturing was successfully prolonged. Due to the growth of the Thermoplastic composites Research Center TPRC, hosted by the group of Production Technology, an increase in research and number of PhD students is expected.

136

8.1 Automated Composites Manufacturing The first research theme is concerned with the cost-effective application of advanced continuous fibre reinforced composites. The breakthrough of this type of materials in various applications has occurred to a smaller extent than might have been expected, mainly due to their high costs of manufacturing. Thermoplastic composites in particular have the potential to overcome these hurdles. In general, research in the PT group starts from a thorough analysis of the deformation and flow mechanisms involved during manufacturing and the modelling of these mechanisms. Design tools are developed to support the production of composite structures with modern techniques. The aim of these design tools is mostly to optimise the processing conditions in order to obtain a composite component having a prescribed shape or combination of materials properties.

High Precision Composites Moulding Friction in composite forming processes is studied within the PhD project of Ir. Sachs, financed by TPRC. Multi-scale models (solving Reynolds’ equation at the meso level) appear to capture the phenomena observed during the experiments. Ir. Sachs followed up on the work of Dr. Ten Thije on friction of composites as a function of pressure, sliding velocity and temperatures up to 400°C. In this way for a number of materials with different architecture the friction behaviour was identified. This so-called Stribeck behaviour was implemented in finite element software and validated with use of experiments on different composite architectures. A clear improvement in prediction of wrinkling behaviour in multilayer laminates was obtained. Next to friction also the material behaviour of the composite plays a significant role in forming. Ir. Haanappel continued his project within the TPRC on ‘complex stamp forming’, focussing on press forming of locally reinforced (i.e. tailored) thermoplastic composite blanks, manufactured by a tape placement process. On the basis of dedicated sample geometries and DMA, parameters for constitutive models could be identified for unidirectionally reinforced materials at forming temperatures. These models have been integrated in FE-software and were validated with use of demonstrator parts. Since the work of Haanappel and Sachs revealed some limitations of modelling multilayered composites by including all plies individually a project on multilayer modeling was started. Ir. Wolthuizen started on the project with the objective of developing a multilayered shell element for composites forming. By omitting the modelling of each layer a gain in stability and calculation time is expected since contact between the plies is simplified. However, a procedure has to be implemented which is capable of incorporating intra-ply shear locally within the element. Ir. Grouve continued his research on the laser assisted tape placement process within the Clean Sky initiative. Here, the aim is to consolidate the thermoplastic tape ‘in situ’ after rapid local heating by means of fibre lasers. In order to identify the sensitivity of the weld process to the process settings an experimental peel test set-up was developed with the objective to gain insight in the behaviour at high heating and cooling rates, finally leading to a process window for in-situ tape placement. The mechanical behaviour of fibre bundles during textile composite processing was the subject of the PhD research by Ir. Cornelissen. The micro-scale phenomena between the filaments are being investigated in order to predict the mesoscopic behaviour of the bundles during e.g. tension, bending, shear and compaction of technical textiles. In order to obtain friction values for fiber-fiber as well as tool-fiber friction Ir. Cornelissen developed an experimental set-up. Measurements on a number of fibers at various conditions have been carried out. A model was developed to incorporate micro contacts and surface roughness into the macro model. The modelling approach was successfully validated with experimental results on the basis of a narrow strip of woven fabric. The friction measurements on this material were confirmed by measurements with the aforementioned set-up used by mr. Sachs. Ir. Van Ravenshorst developed a braiding simulation tool for prediction of among others fiber angles and braid densities. At the end of the year also an optimization algorithm was developed that is able to optimize the braiding process in order to obtain the required (optimal) fiber angles. It can be used to reduce lead-time and cost related to engineering, physical testing and over-dimensioning. The

137

optimization procedure was verified by demonstrator parts that were braided at the facility of the project partner. A number of improvements with respect to the optimized process setting could be carried out and subsequently the software was applied on a first industrial application. MSc. Liu continued her project on advanced joining processes. The objective is to develop guidelines for thermoplastic composites joining processes. In the first phase a number of joint types have been evaluated (e.g. co-consolidated lap joints) and modelled with the help of finite elements. It is aimed for deeper insight in the relation between joining process and its conditions, the materials and their combinations and the properties of the joint in real life loading situations. On the basis of this insight, a number of lap joints have been prepared with optimized geometry. Although there was a clear trend towards shear of the interface, the results proved that the lap-joint geometry is insufficient to compare different joining methods.

8.2 Performance of Advanced Materials The second research theme involves a better understanding of the mechanics of new materials, focusing on the physical properties of the component and taking into account the production process used. An increasing range of properties is being considered, from thermo-mechanical properties such as stiffness and structural integrity, to optical and electromagnetic properties on the short and the long term. Materials with ‘added functionality’ (e.g. composites with integrated sensors and actuators or even self-healing capacity) receive growing interest. The current research projects in this theme are: • long term performance of thermoplastics • active composites • transverse reinforcement of composite materials • friction stir processing of light metals • impact properties of thermoplastic joints

Long term performance of thermoplastics The PT group investigates the long term performance of non-reinforced pipework. Condition Monitoring in plastic pipe gas distribution networks can assist in ‘smart maintenance’, replacing gas pipes (at the end of their design lifetime) only when necessary. Physical ageing decreases the fracture toughness which can lead to premature failure. The long term performance as measured with pressurised pipe tests can be predicted using models (dr. Govaert, TU/e) fitted with elementary experiments such as tensile and compression testing on specimens of different ages. It was shown that the brittle-to-ductile transition temperature increases with the physical age of PVC. Dr Visser successfully defended his PhD thesis on this subject in 2010. The project is proceeded by Drent MSc, who will study the long term performance of more recent types of PVC and will pay attention to the manufacturing process in relation to physical aging and material characterization. After a short break Dr. Demcenko continued his research on ultrasonic methods for determination of the physical age, funded via the MEA. He got support from MSc. Ravanan. His research is funded via the TTI Wetsus. Dr. Cicenas continued the research on the ultrasonic inspection of asbestos pipes as a postdoctoral fellow with the support of Dr. Demcenko, also in cooperation with Wetsus. The research on ultrasonic inspection was prolonged successfully. Dr Cicenas left our group in February. Then, Dr. Demcenko continued also this research. Active Composites Composite damage is known to be difficult or impossible to detect visually during regular inspection. However, composites are well suited to embed strain sensors such as fibre optics. In the ongoing PhD project of Ir. Ooijevaar the measured dynamic response of composite structures is used to detect and localise damage. His project on structural health monitoring is funded by the Clean Sky initiative. In addition to sensing, also actuation mechanisms can be incorporated in composite materials, leading to active light weight structures. This is investigated in the Clean Sky funded project of

138

Paternoster MSc for the application of intelligent helicopter rotor blades. Both Clean Sky projects are conducted in cooperation with the Structural Dynamics and Acoustics group of prof. De Boer. Transverse reinforcement Carbon nanofibres can be grown on microfibres by means of catalytic deposition. This can be used in composite materials to improve the properties transverse to the fibre orientation. The four research positions within the two participating groups (PT and CPM, prof. Lefferts) were filled in the course of the year. The first efforts were devoted to scale up the CNF deposition process. The project of Dr. Koissin, postdoctoral fellow, is financed by STW. Double cantilever beam tests showed a significant improvement of the toughness properties using carbon nanofibres. Friction Stir Processing Friction Stir Welding is a solid forming process, suited for relatively low temperature joining of e.g. aerospace Aluminium alloys. It proves to be possible to extend this process by means of adding an extra material during stir welding. Dr. Christoulis developed a set-up to realize this concept on the FSW equipment installed in the course of last year. Experiments indicate that deposition of thin layers of protective, pure aluminium on aerospace Aluminium alloys is possible. Related to this, the PhD project of Ir. Van der Stelt focuses on process modeling in order to achieve better understanding and process optimization. MSc Shaojie Liu continues this work. Impact properties of thermoplastic joints Currently a lot of research efforts are put into joining methods for thermoplastic composites. Dr. Ilin continued the research on a project especially dedicated to improvement of impact properties of a new type of joint for thermoplastic composites. Essential in his research is the ability to understand and incorporate failure into numerical models for predicting joint impact properties. By combining XFEM, especially for non-layered nearly isotropic composites, and transverse crack and delamination modelling all failure modes can be captured. In 2012 the developed models were extended and successfully verified using different experimental tests. The research will be continued towards fast models and guidelines for design. Mechanical deformation of austenite stainless steel Finally, a joint PhD project is carried out with the Technical Mechanics group by ir. Hilkhuijsen. The project is related to modelling the mechanical and transformation behaviour of various types of austenitic stainless steels during plastic deformation for proportional and non-proportional deformation paths. Sustainable materials Sustainable and bio-based materials are getting more and more attraction. In the project of ir. Jansma, funded by the GO-EFRO programme, natural fibers in the combination of bio-based thermoplastic resins are investigated with respect to their application in consumer products. Special attention is paid to structural and long-term performance properties of these class of materials. The objective of the project is to develop optimized materials for the aforementioned market segment. The project of Iqbal Rasheed can be placed in this cluster as well. The project is funded by the DPI value centre. The topic of his research is compression molding of thermoplastic composite flakes, that may originate from production waste during composites processing or end-of-life scrap. In order to assess the mechanical properties and their variance a screening of different compression molded plates using different materials and flake sizes has been performed, while during the same period simple models for stiffness and strength have been developed. Model results could partially be validated, however the experimental basis has to be extended to other flake sized and geometries as well. All activities within the programme are related to the research theme “Computational and Experimental Mechanics”.

8. Short description of sub programmes related to research school EM 8.1 MultiScale Simulation Techniques

8.1.1 Hierarchical MultiScale Modeling

This research will be at the junction of three areas: Dynamic unstructured grids and their refinement, hierarchical data structures for coarsening and micro-macro methods, and coupling of various techniques and fields across the scales. The idea is to provide new ways of coupling between particle and continuum methods for multi-scale modeling, not only relying on a future increase of available computing power, but also keeping massive parallelization in mind. At present, hierarchical hash tables and multilevel grids for efficient simulation of poly-disperse systems and FEM/DEM coupling for fluid particle interaction problems e.g. porous media, fluidized beds is being explored.

8.1.2 Computational methods for scale bridging in composite materials The computational modeling of fracture in composites, concrete, and other cohesive granular materials will be performed and analyzed following a hierarchical multi-scale approach, involving

145

parallelization and tree-data-structures for both the particle analysis and the continuum analysis. A question from the mechanics side is the understanding of the formation of cracks and the ability to predict the conditions (mechanical, environmental) under which they occur or are triggered. Are the small scales more important than the large ones? This makes crack growth (from its initial micro-state up to dimensions leading to failure of a material or a structure) a research issue of paramount importance – and a challenge from the algorithmic and numerical point of view.

8.1.3 Jamming and Creep in Granular Materials The project is addressed to probe the connections between jamming, creep, shear banding and microstructures in numerical simulations of Brownian and non-Brownian systems with various interaction forces, shear rates, stress regimes at multiple scales. Computational multi-scale modelling of super-dispersed multiphase flows The goal of the research is the development of good numerical models for dry granular flow, which is of interest in many industrial processes and geophysics. Granular material shows both solid and fluid behavior. Closed continuous models for granular flow only exist for certain cases, while Discrete Particle Models (DPM) are unfeasible for large-scale simulations. Therefore the work focuses on a DG finite element model for heterogeneous multiscale modelling of polydisperse, nonuniform dry granular flows, which allows both efficient and reliable numerical simulations.

8.2 Instability in MultiScale materials Traditionally instabilities have been viewed as an inconvenience, with research focusing on how to avoid them. Instead they can be exploited to create new materials with improved and switchable properties. Many technological applications, including acoustics, optics and electronics, require the development of new materials with improved and possibly even tunable properties. Particular attention is reserved to materials characterized by a regular micro-structure. Both Nature and technological applications make extensive use of materials to achieve different properties and attributes. Examples are given by phononic/photonic crystals, sensors, super-hydrophobic surfaces and the surface structure of beetles and fishes. We explore the nonlinear microscopic behavior and failure of such materials. This investigation will pave the road to the use of the pattern switch occurring at instability for creating a new class of materials with switchable functionalities. Instability induced pattern switches in granular crystals. The specific project refers to the investigation of large deformation behavior of two and three-dimensional granular crystals consisting of elastic and rigid particles. The investigation takes the form of numerical and experimental tests, which confirm the existence of global pattern transformation triggered by the applied load. The findings have consequences for the fabrication of tunable granular meta-materials and energy and shock absorbers. The implementation of a continuum model able to describe the evolution of the material structure is a further goal of the project.

8.3 Bridging the gap between particulate systems and continuum theory Structural Dynamics and Acoustic. In this project sound wave propagation through different types of dry confined granular systems is studied with three-dimensional discrete element simulations, theory and experiments. The influence of several micro-scale properties: friction, dissipation, particle rotation, and contact disorder, on the macro-scale sound wave propagation characteristics are investigated.

146

Experiments, analyzed with the “Spectral Ratio Technique”, make it possible to extract frequency-dependent propagation velocities and attenuation. An improved set-up for future investigations is proposed in order to better understand dispersion and propagation of sound in granular materials. The full dispersion relation of a Face-Centered-Cubic lattice is derived from a theoretical analysis that involves translations, tangential elasticity, and rotations. The additional displacement and rotation modes and the energy conversion between them is studied using discrete element simulations. Simulations and theory are in perfect quantitative agreement for the regular lattices examined. A big step in complexity is made by investigating the sound propagation in a realistic tablet made of a sintered frictional and cohesive polydisperse powder and prepared in different ways. These simulations nicely display history dependence and the effect of different material parameters on sound propagation in particulate solids.

8.3.2 Constitutive modeling of anisotropic granular materials Dense granular materials behave differently from fluids or solids. Classical continuum theories fail in describing granular matter when the onset of flowing is approached, and his properties, as dilatancy, yield limit, anisotropy and ratcheting. In fact, the behavior at macro-scale is strongly related to smaller-scale field variables and kinetic processes. The goal is to solve this lack with a multiscale approach, coupling discrete and continuum. Getting insights from Discrete Element Method (DEM) simulations a continuum in-homogeneous model will be developed and implemented to describe the macroscopic behavior of the material in terms of homogeneous local properties. A first step is the development of a local constitutive model with anisotropy The model involves only scalar quantities and a new ingredient, the anisotropy. As opposed to isotropic materials, shear strain can cause e.g. dilation and hence compressive stresses, when anisotropy is considered. The local field variables are expressed in terms of material parameters, measured by DEM simulations, leading to a complete calibration of the predictive model.

8.4 Mechanics of Forming Processes Non-Newtonian behavior of granular flows in nano-channels. Highly confined fluid or particle flows typically show strongly non-Newtonian behavior. A channel geometry is often used to study the inhomogeneous behavior of strongly confined fluids. The understanding of these non-Newtonian fluid problems is still very limited, while gaining a deeper insight into these systems is becoming increasingly important with the rise of microfluidic and nanofluidic applications, such as lab-on-a-chip device. Very similar phenomenology (i.e. layering, anisotropy) is observed in many particle systems. The goal of the study is to investigate the non-Newtonian transport properties of granular flows, investigate the effect of wall-fluid interaction, surface roughness and wall-morphology on the material behavior. Molecular dynamics simulations are used to investigate various physical properties.

8.4.2 Size segregation in dense granular avalanche flows Dense, dry granular avalanches are very efficient at sorting the larger particles towards the free surface of the flow, and finer grains towards the base, through the combined processes of kinetic sieving and squeeze expulsion. This generates an inversely graded particle-size distribution, which is fundamental to a variety of pattern formation mechanisms, as well as subtle size-mobility feedback effects, leading to the formation of coarse-grained lateral levees that create channels in geophysical flows, enhancing their run-out.

147

A continuum model of size segregation for dense granular free surface flows have been developed. A large number of analytical and numerical solutions to these equation have been constructed and compared to experiments. The focus of this research is now on using this model to explain phenomena caused by segregation. These include pattern formation in rotation drums, levee formation in geophysical flows, particle size structure of a flowing finite mass of material in avalanches and axial segregation in long rotating cylinders. Modeling of Long-range interaction forces and clustering. Clustering in granular material is since long a hard topic. It is a generic and paradigmatic example for the special behavior and [properties of granular matter: long and high densities co-exist, large gradients and shocks occur, both solid and liquid-like behaviors are observed inside the clusters. The objective of the project is to develop a three dimensional Molecular Dynamics (MD) environment and hydrodynamic theory for modeling long-range interaction forces based on hierarchical algorithms, to reproduce clustering of particles.

8.5 Discrete particle self-healing material models Using an advanced history dependent contact model for DEM simulations, including elasto-plasticity, viscosity, adhesion, and friction, pressure-sintered tablets are formed from primary particles. These tablets are subjected to unconfined uni-axial compression until and beyond failure. For fast and slow deformation we observe ductile-like and brittle softening, respectively. We propose a model for local self-healing that allows damage to heal during loading such that the material strength of the sample increases and failure/softening is delayed to larger strains. Local healing is achieved by increasing the (attractive) contact adhesion forces for those particles involved in a potentially breaking contact. By healing and sintering, the material strength is enhanced, i.e. the material fails at larger strains and reaches larger maximal stress values, when any of the parameters (a) – (c) is increased. For moderate damage detection sensitivities, the material strength increases with both increasing healing rate and increasing adhesion of the healed contacts. For very large adhesion between the healed contacts an interesting instability with strong (brittle) fluctuations of the healed material’s strength is observed.

8.5.1 Sintering – Modeling of Pressure-, Temperature-, or Time-Dependent Contacts In most realistic situations, where particles come in contact, it can NOT be assumed that the contact properties are independent of pressure, temperature or time. Therefore, this project involves pressure-, temperature-, and time-dependent contact properties and their influence on the macroscopic powder flow behavior. Sintering is chosen as one possible example and starting point, where all these phenomena are relevant. The goal of this project is to model the particles in contact, before the particles lose their identity. For this, temperature- and pressure-dependent contact models have to be developed in parallel to contact-measurements (with Kappl, Mainz). The many-particle simulations will then be adapted to the materials used and experimentally validated (with Tomas, Magdeburg). As the result of the project, a verified numerical model for the sintering process of many particles will become available. This will then be used for the micro-macro transition in order to obtain better theoretical constitutive relations for a macroscopic description based on the contact-mechanics and -physics.

148

8.6 Discrete particle and experimental characterization for dry and cohesive powders The overarching aim of the PARDEM project is to provide high quality training, contributing to the development of a new generation of multidisciplinary researchers able to work within the newly emerging supra-disciplinary field of Discrete Element Method (DEM) computational simulations of granular processes. Particle systems and granular materials are in abundance in nature and constitute over 75% of all raw material feedstock to industry. They present many challenges for innovation and fundamental science, to solve problems in areas as diverse as natural disasters and unsolved industrial material handling issues which incur extensive economic losses. Attempts to improve the situation with classical continuum theory and standard numerical methods and design tools cannot always be successful because they have to ignore the fact that particle systems consist of discrete objects. A promising interdisciplinary alternative is DEM which follows in detail the motion and interaction of particle assemblies. Even though the method is established in academia, innovation and challenges await those who apply it to realistic particle systems of industrial relevance. Within this ITN, an intersectoral training program will reduce the shortage of R&D engineers experienced in DEM while – in parallel – several original research questions will be answered, related to the transition from very small discrete particles up to industrial processes and plants. Both objectives are necessary to formulate methods/standards for code validation and model calibration so that DEM can be transformed from a largely scientific tool into a widely adopted industrial method providing an advantage for the competitiveness of the EU economy due to reduced development times and more efficient processes. The high level of industry interest in finding elegant solutions to these problems is evident from the enthusiastic involvement of major industry players Nestlé, BASF, Zeppelin and Procter & Gamble as full partners in the project.
