InternationalConference on Advances in

Experimental Mechanics

Welcome to the University of Exeter and the BSSM’s 11th International Conference on Advances in Experimental Mechanics.

The BSSM sits at the interface between industry, academia and the wider engineering community and promotes their interaction to ensure the wide dissemination of new ideas and best practice in the field of engineering measurement.

This conference focuses on research which advances experimental techniques across the very widest range of applications in mechanics, including stress, strain and vibration analysis.

In addition to the main conference, this year’s event includes all the ‘traditional extras’, including the BSSM Measurements Lecture, the annual BSSM EMex exhibition of experimental mechanics, the BSSM Young Stress Analyst Competition and BSSM short courses.

We are looking forward to a technically excellent conference and we are very grateful to the authors for their efforts in producing their contributions to the programme.

We also thank the organising committee without whom the conference would not have been be possible, in particular Mrs Amanda Boaler (conference secretariat), Mrs Biana Gale (EMex), Prof Simon Quinn and Dr Rachael Tighe (for providing continuity with previous BSSM conferences), and Prof Stephen Eichorn (local representative).

We hope you enjoy the conference and its many events, all of which are described in this handbook. If you require any assistance during the conference please do not hesitate to contact the Conference main desk for help.

Prof Chris Smith (University of Exeter)

BSSM Measurements Lecture‘Studying fracture by synchrotron computed tomography, image correlation and X-ray diffraction’

Prof. James Marrow, University of Oxford, UK.

This presentation summarises progress in work to observe deformation and fracture using X-ray tomography and digital volume correlation to measure three-dimensional strain fields. In particular, high precision synchrotron diffraction studies on strained samples and within the fracture process zone of propagating cracks provide new insights into elastic and inelastic deformation by micro cracking in polygranular nuclear graphite . Microcracked fracture process zones are common to quasi-brittle materials as diverse as high toughness monolithic ceramics, polymeric and natural biological composites, geological minerals and even volcanic structures. Experimental methods that support the study and modeling of damage development are thus important to a wide range of problems.

Biography:

Prof. James Marrow is the James Martin Chair in Energy Materials, and co-directs the Nuclear Programme in the Oxford Martin School. He joined the Oxford University Department of Materials in September 2010, from Manchester where he directed the Materials Performance Centre. He obtained his undergraduate degree and PhD in Materials Science at Cambridge University, and became a lecturer at Manchester following postdoctoral research at Oxford and Birmingham Universities. Prof. Marrow’s research focuses on degradation of structural materials and the role of microstructure, investigating fundamental mechanisms of damage accumulation using novel materials characterisation techniques. He has pioneered imaging methods for quantification and observation of cracks in engineering materials, and is now leading in the area of three-dimensional studies of damage, using high-resolution X-ray computed tomography and measurement of the three-dimensional full field displacements by digital volume correlation. Prof. Marrow has established a close interaction with the Diamond Light Source synchrotron facility at the Rutherford Appleton Laboratory. This work has pioneered the three-dimensional characterisation of damage processes in energy and nuclear materials, supporting the validation of simulation tools to forward predict materials performance.

Plenary Lectures‘Unravelling the role of internal boundaries in lath martensite plasticity’

Dr Johan Hoefnagels, Technische Universiteit Eindhoven, The Netherlands

The complex substructure of lath martensite with its internal (packet/block/sub-block) boundaries is the key ingredient that provides high strength to advance steels. Martensite is known as hard and brittle, but recent evidence shows significant plasticity before fracture. The exact reason is unknown due to the complexity of mechanical testing at such small scales. We tackle this challenge by employing a highly-sensitive home-built nano-force tensile tester to perform well-defined uniaxial tensile tests on lath martensite micro-specimens, which are milled out from a single packet or single block and selected to have a small, varying number of through-thickness block or sub-block boundaries, at specified orientations to the loading direction. Consistently, crystallographic slip is activated on the {110}<111> slip system with the highest Schmid. Interestingly, not only block but also sub-block boundaries act as barriers to dislocation motion, both following a Hall-Petch like behavior. Sub-block boundary strengthening is only slightly less effective than block boundary strengthening, although dislocation motion can cross sub-block but not block boundaries. Surprisingly, under favorable boundary orientation an interesting new deformation micro-mechanism unobserved in literature, i.e. boundary sliding, become active and its competition with crystallographic slip determines the resulting plastic behavior

Biography:

Johan Hoefnagels obtained his PhD degree in Applied Physics at from the Eindhoven University of Technology in 2005 on advanced optical diagnostics of surface processes during thin film deposition. He acquired 2+ years of research experience in the US at SUNY, NIST, CSM, and Harvard University and became assistant professor of mechanical engineering at the TU/e directly after his PhD. His research focuses on experimental micromechanics of thin films and interfaces, studying the systems’ mechanics by integrated mechanical-microscopic characterization of underlying micro-structures. Topics include advanced materials, interfaces in micro-systems, miniaturization and MEMS, flexible and stretchable electronics, and micro-mechanics of advanced steels.

Plenary LecturesMultifunctional and Programmable Cellular Materials with Self-Similar Hierarchy’

Prof. Ashkan Vaziri, Northeastern University, USA

The properties of traditional materials are fixed by their atomic or molecular arrangements and typically difficult to alter further due to the constraints of sub continuum forces and relatively closely packed microstructure. Thus developing and engineering new materials with either extreme properties or a non-traditional combination of behavior becomes extremely challenging. This fundamental limitation of the properties can however be challenged by first noting that the overall properties of a given material originate not just from the atomic constituents but their mutual arrangements, for instance, their lattice structure. Cellular materials, whose structure is made up through scaling up of a fundamental geometrical unit cell can be seen as analogs of natural crystals and thus serve as an excellent template for metamaterial development. More importantly, the meso-level organization and large free spaces inside cellular structures make imparting geometrical changes in their underlying structure much easier compared to traditional materials or composites. Since the overall properties of cellular materials are directly linked to the geometry of the underlying unit cell, it becomes possible to herald materials capable of reversible change of properties through physical stimuli hitherto impractical at large scale except in special cases such as piezoelectric, shape memory or specially designed glass materials.

In this presentation, I discuss a novel class of architectured cellular materials, which are capable of dramatic but controlled shape and size change through alteration of their underlying topological hierarchy. This high degree of geometrical change can yield a correspondingly wide bracket of mechanical and multifunctional behavior since the overall properties of cellular materials are intrinsically tied to their underlying topology. Results will be presented related to investigating the static and dynamic elastic behaviour of these structures. I will discuss that the change in shape and size of these hierarchical structures can significantly tailor their responses, and they can be effectively used to tune the properties multifunctional hierarchical cellular structures.
