An Improved 3D Adaptive EFG Method for Forging and Extrusion Analysiswith Thermal Coupling in LS-DYNA

C. T. Wu - Livermore Software Technology CorporationHongsheng Lu Shanghai Hengstar Technology Co. Ltd.

Abstract: The 3D adaptive EFG methodusing conventional moving least-squareapproximation or fast transformationmethod [1] has been successfully appliedto metal forging and extrusion analysisthanks to its high accuracy in dealingwith large material deformation [2] inLS-DYNA. Recently, a meshfree convexapproximation [3-5] was developed to bean alternative in the large deformationanalysis. However, its application to the

adaptive method has not beeninvestigated.

In this paper, an improved version of 3Dadaptive EFG method with emphasizingon the modified maximum entropyapproximation, whose approximation isnon-negative and owns Korncker-Deltapropriety at the boundary, is presented.The thermal effect in forging andextrusion problem is considered, and ascheme to interpolate the thermal statevariables during the adaptive procedure

is proposed

An MPP Version of the Electromagnetism Module in LS-DYNA for 3D CoupledMechanical-Thermal-Electromagnetic Simulations

P. LEplattenier, Livermore Software Technology Corporation C. Ashcraft, Livermore Software Technology CorporationI. Ulacia, Mondragon Goi Eskola Politeknikoa

Abstract: A new electromagnetismmodule is being developed in LS-DYNAfor coupledmechanical/thermal/electromagneticsimulations. One of the main applicationsof this module is Electromagnetic MetalForming (EMF). The electromagneticfields are solved using a Finite ElementMethod (FEM) for the conductors coupledwith a Boundary Element Method (BEM)

for the surrounding air/insulators. Bothmethods use elements based on discretedifferential forms for improved accuracy.

Recently, a Massively Parallel Processing(MPP) version of the EM module wasdeveloped allowing sharing the CPU andmemory between different processors

and thus faster computations on largerproblems. The implementation of theFEM and BEM in MPP will be presented.The EM module will then be illustrated onan actual EMF case. Experimental andnumerical results will be compared andthe speed-up of the MPP version will bestudied.

Finally, a new contact capability for the

electromagnetic fields will be presentedand illustrated on a rail gun simulation.

New Features in LS-DYNA HYBRID Version

Satish Pathy , Livermore Software Technology CorporationJason Wang , Livermore Software Technology CorporationNick Meng , Intel Corporation, Software and Services Group

Abstract: Numerical noise arising fromdifferent MPP core counts compels usersto fix the number of cores used by LS-DYNA MPP e.g. during a vehicledevelopment program. This fixed corecount limits job turn-around time andflexibility in managing computingresources. In addition, using a largenumber of cores for calculationsdiminishes scalability with pure MPP.

LS-DYNA HYBRID addresses these

issues through the use of both MPI +OpenMP technology. LS-DYNA HYBRID isable to produce consistent numericalresults when changing the number ofOpenMP threads thereby reducing jobturnaround time. In addition, LS-DYNAHYBRID can greatly reduce the numberof processors involved in messagepassing and achieve much betterscalability over large number of cores.Furthermore, for the implicit applicationsLS-DYNA HYBRID not only reduces thememory requirement per node but alsodecreases IO activity.

Currently, LSTC and Intel teams areworking together with a customer toevaluate LS-DYNA HYBRID code using acustom QA (Quality Assurance) suite.The consistency and performance will bediscussed in this paper.

LS-DYNA crash-analysis modelof the PACE F1 car,

under the guidance ofDr. Greg Jensen,

Brigham Young University

Link to the full article: http://www.lstc.com/pdf/a_pace_car.pdf

INTRODUCTION

Vehicle crash analysis has historicallybeen the postmortem physical test thatcaused engineers and manufacturers tolaunch a flurry of product modificationsand redesign, engineering changeorders, and even the eventual demise ofa car model. One need only think of theFord Pinto or Chevy Corvair as examplesof models that were designed,manufactured, and sold long before the

automotive industry knew how unsafesome of their cars really were. In theearly 60s a number of analysis codeswere developed to assist engineering inthe a priori investigation of designs tobetter predict when a given part orassembly would fail in real life. Howeverlittle was done until the mid 70s whenDr. John O. Hallquist developed the firstanalysis code that attempted to analyze

the impact between two bodies. Thisearly DYNA has matured into a widelyused crash analysis tool that todaycatches many design flaws long beforethe first prototype is ever realized.Today, the correct use of this tool iscredited with saving millions indevelopment costs, reducing untoldnumbers of vehicle recalls and ultimately

saving un-numbered lives byempowering engineers with the ability tovirtually crash their design until theyarrive at an optimally safe survival cellfor the occupants.

This report will focus on work donecollaboratively by BYU MechanicalEngineering and LS-DYNA engineeringcreating a crash simulation on the PaceF1 race car. From February to April2010, BYU students met with industryexpert Suri Bala to create a best possible

frontal impact simulation. Studentsworked on the model 6-10 hours a weekwith a one-hour coaching session fromSuri each week. The results of this workare enlisted below with a detaileddescription of the methodology adopted,plan of action and finally, the progressthat was made.

COLLABORATION TOOLS

As all interactions between BYUMechanical Engineering students andLSTC engineer Suri Bala were doneremotely, certain collaboration toolswere very useful in organizing theprojects work and results.

D3View

D3VIEW, an online collaboration tool forLS-DYNA projects, was used as arepository for all work done. UsingD3VIEW made it easy for BYU students

to share current progress on the model,information about the car, media(photographs and videos on the car) thatabetted functioning of variouscomponents, and other questions easilywith Suri Bala. The version controlfeature of D3VIEW was particularlyuseful in backing up and logging theprogression of the car model. Themilestone and tasks features were alsouseful in helping everyone working onthe project, know specifically the tasksthat needed to be completed by eachstudent each week and also when weeklymeetings would be held. Once the LS-DYNA simulation results were available,D3VIEW was used extensively to reviewmodel information, time-history plotsand media files such as images andmovies generated from D3PLOTs andBINOUTs files.

Cisco Webex

For review of the each weeks work, andfor instruction, Cisco Webex, an onlinedesktop sharing application, was used toshare desktops between BYU studentsand Suri Bala. This tool provedextremely useful in allowing Suri toreview the students work, and use otherinstructional material to teach the BYU

students about LS-DYNA and themodeling process. Additionally,modifications could be madespontaneously which helped to quickenthe overall process of model creation, asdescribed below.

MODEL CREATION

Discretization Process

Creating a discretized model of the PACEcar began with identifying the most basicstructural components of the car andmeshing them. Functionality of thosebasic structural components and howthey connected with various othercomponents was additionally important.For example, modeling the suspensionrequired a detailed comprehension of itsmechanics and dynamic movements, asdiscussed later in this section. Thecomponents which were first meshed

include the front wing, nose cone,nose/wing connection pieces, structuralbulkheads, and the monocoque body(See Appendix A for a detailed list ofeach part). The meshing process beganby cleaning the part geometry in NX.Several features and geometricalconstructions were inaccurate andinconsistent to the actual part produced:inconsistent in that they were either notthe same as the actual component withregards to geometry or shape, or hadCAD features that would not allowcorrect meshing. De-featuring thegeometry and exporting it to a STEP filein NX was the next step. The STEP fileswere then imported into Hypermesh andmeshed using a 2D shell mesh for thethinner/ hollow parts (nose cone, frontwing, monocoque body) and a 3D solidtetramesh for the bulkier parts

(bulkheads, nose/wing connectionpieces). The mesh was then checkedand refined in several iterationsthroughout the project to get rid of anymisshapen elements. Mesh quality wasan important part of obtaining accurateresults mesh element size andvariables such as interior angle and

warpage were kept under control withina range of acceptable values. Stayingwithin that range increased the accuracyand quality of the mesh which in turnproduced more realistic results. Meshquality is discussed in short below.

Subsequent to meshing the mainstructural components, we focused onadding more detailed components to themodel. The wheel assemblies along withbeam elements representing thesuspension struts were similarly meshedand added to the assembly. We thenmeshed several of the suspension andsteering components of the car keeping

in mind which components would provestructurally effective (in the core senseand which would be addendums to thestructure (provide structure but do notenhance structural integrity by much).As important as meshing these variouscomponents were, was the task ofconnecting the components as they wereconnected in the car and then modelingthese connections for crash analysis. Theaccomplishment of this task was doneusing LS PrePost. The meshed geometryfrom Hypermesh was imported into LSPrePost as an LS DYNA keyword file andthen saved as a keyword file within LSPrePost (Note: Some components were

not meshed in Hypermesh but weredirectly imported into LS PrePost andmeshed therein). Within LS PrePostnodes were created for the type of

joint/feature connecting thesecomponents. These components and

their motion were modeled using severaldifferent connection methods which willbe discussed in the Part to PartConnections section of this report. Thefixed and revolving brackets weremeshed as 2D shell elements and theirquality was checked within LS PrePost.The suspension was modeled byattaching spring elements to therevolving and fixed brackets through

revolute joints, then connecting thesmall revolving bracket to the large fixedbracket and rigid strut element throughadditional revolute joints. Theseconnections allow the modeled pieces toas closely as possible behave like theactual components which are installed onthe car, but at the same time are notmodeled only for the purpose of correctrepresentation with the car. Becausethere is load transfer between thesecomponents and that they enabledeflection (hence absorption), theseconnections were quintessential toaccurate modeling.

Mass Exercising Try a new Cultureon for Size

The Beijing Government is pushing massexercising again to increase the health ofthe nation. Mao Ze Dong began massexercising in the 1950s and many of myChinese friends grew up doing suchexercises in school.

While working at Kingold Group in China,we did mass exercises at 11am andagain at 3pm. We did the same exercise

everyday and eventually I was able tomemorize it and do it without any aides,or the need to clumsily mimic others. MyChinese coworkers thought it washilarious to watch me because I, ofcourse, wasnt doing it with natural flowthat most of them performed with. Itwas kind of like watching Jay Leno doinga hardcore rap song about rollin through

the rough part of town.

However, there was some camaraderiethat I could feel and it was invigoratingto get up in the afternoon and get myblood flowing. Some days I did feel likewe were all being magically brainwashedas we moved in unison, but I dont see

Overall, it was a very different culturalexperience. I participated and wasrewarded with greater trust, deeper

friendships, moments of laughter,greater understanding of the benefits ofChinese culture, and I was able to skipthe afternoon nodding off that typicallyhappens after eating too large of a lunch.

I think we should be willing to participatein other peoples culture. Try it out. Thatdoesnt mean we have to try their

religious ceremonies and worship othergods if we dont believe it is the rightthing to do. It just means we can try oncultural opportunities for size. We willstart to realize that a different cultureoffers benefits our culture may not offer.

We realize that our way doesnt have tobe the only right way. In fact, theremight even be something better outthere. And even if it turns out that sucha cultural activity doesnt fit us at all, atleast we can understand just a little bitmore what it means to be Chinese orRussian or French.

Artist concept of BP Piscium,a more evolved version of our Sun.

Chandra Finds Evidence for StellarCannibalism

Illustration credit: CXC/M. Weiss

ht t p: / / www. nasa. gov/ mi s si on_ pages/ chandr a/ news/ 10- 118. ht ml

Evidence that a star has recentlyengulfed a companion star or a giantplanet has been found using NASA'sChandra X-ray Observatory. The likelyexistence of such a "cannibal" star

provides new insight into how stars andthe planets around them may interact asthey age.

The star in question, known as BPPiscium (BP Psc), appears to be a moreevolved version of our Sun, but with adusty and gaseous disk surrounding it. Apair of jets several light years longblasting out of the system in oppositedirections has also been seen in opticaldata. While the disk and jets arecharacteristics of a very young star,several clues -- including the new resultsfrom Chandra -- suggest that BP Psc isnot what it originally appeared to be.

Instead, astronomers have suggestedthat BP Psc is an old star in its so-calledred giant phase. And, rather than beinghallmarks of its youth, the disk and jets

are, in fact, remnants of a recent andcatastrophic interaction whereby anearby star or giant planet wasconsumed by BP Psc.

When stars like the Sun begin to run ofnuclear fuel, they expand and shed theirouter layers. Our Sun, for example, isexpected to swell so that it nearly

reaches or possibly engulfs Earth, as itbecomes a red giant star.

"It appears that BP Psc represents astar-eat-star Universe, or maybe a star-

eat-planet one," said Joel Kastner of theRochester Institute of Technology, wholed the Chandra study. "Either way, it

just shows it's not always friendly outthere."

Several pieces of information have ledastronomers to rethink how old BP Pscmight be. First, BP Psc is not locatednear any star-forming cloud, and thereare no other known young stars in its

immediate vicinity. Secondly, in commonwith most elderly stars, its atmospherecontains only a small amount of lithium.Thirdly, its surface gravity appears to betoo weak for a young star and insteadmatches up with one of an old red giant.

Chandra adds to this story. Young, low-mass stars are brighter than most otherstars in X-rays, and so X-ray

observations can be used as a sign ofhow old a star may be. Chandra doesdetect X-rays from BP Psc, but at a ratethat is too low to be from a young star.Instead, the X-ray emission ratemeasured for BP Psc is consistent withthat of rapidly rotating giant stars.

The spectrum of the X-ray emission --that is how the amount of X-rayschanges with wavelength -- is consistentwith flares occurring on the surface ofthe star, or with interactions between thestar and the disk surrounding it. The

magnetic activity of the star itself mightbe generated by a dynamo caused by itsrapid rotation. This rapid rotation can becaused by the engulfment process.

"It seems that BP Psc has beenenergized by its meal," said co-authorRodolfo (Rudy) Montez Jr., also from theRochester Institute of Technology.

The star's surface is obscured throughout

the visible and near-infrared bands, sothe Chandra observation represents thefirst detection at any wavelength of BPPsc itself.

"BP Psc shows us that stars like our Sunmay live quietly for billions of years,"said co-author David Rodriguez fromUCLA, "but when they go, they justmight take a star or planet or two withthem."

Although any close-in planets werepresumably devastated when BP Pscturned into a giant star, a second roundof planet formation might be occurring inthe surrounding disk, hundreds ofmillions of years after the first round. Anew paper using observations with theSpitzer Space Telescope has reportedpossible evidence for a giant planet in

the disk surrounding BP Psc. This mightbe a newly formed planet or one that

was part of the original planetarysystem.

"Exactly how stars might engulf otherstars or planets is a hot topic inastrophysics today," said Kastner. "We

have many important details that we stillneed to work out, so objects like BP Pscare really exciting to find."

These results appeared in TheAstrophysical Journal Letters. Other co-authors on the study were NicolasGrosso of the University of Strasbourg,Ben Zuckerman from UCLA, MarshallPerrin from the Space Telescope ScienceInstitute, Thierry Forveille of the

Grenoble Astrophysics Laboratory inFrance and James Graham fromUniversity of California, Berkeley.

Brief On

The Electromagnetism Module

In LS-DYNA

Author: Pierre L'eplattenier [email protected]

The Electromagnetism module allowsperforming Coupledmechanical/thermal/electromagneticsimulations:

Introduction of electrical currentsin solid conductors

These currents generate magneticfields, electric fields, as well asinduced currents.

The magnetic fields coupled withthe currents generate Lorentzforces on the conductors.

The forces induce motion anddeformation of the conductors.

This motion has an effect on thefields and the currents.

The currents generate Jouleheating in the conductors,changing the temperature, andthus some electromagnetic (aswell as mechanical) properties(conductivity for example).

One application of the module:Magnetic Metal Forming:

A conducting coil induces electricalcurrents in the workpiece.

This creates an electromagneticforce pushing the workpieceagainst the die.

It is a high velocity formingprocess:

o The forming limits can besignificantly increased(80%).

o The springback is reduced.o The wrinkling is reduced.o Shock hardening of the

material.o The amount of energy can

be tightly controlled.o High reproducibility.o No contact between the coil

and the workpiece (onesided die+no friction)

Additional Applications:

Magnetic metal cutting Magnetic metal cutting. Magnetic metal welding (impact

welding). High magnetic pressure

generation Magnetic metal cutting. Magnetic metal welding (impact

welding). High magnetic pressure

generation. Computation of the

stre sses/deformations in coils.

Additional Recently:

MPP version of the EM moduleallows sharing memory and CPUbetween processors, hence fastercomputations on larger cases.

Induced heating (Joule effect). Resistive heating. Electromagnetic contact capability:

rail-gun.

Rail Gun:

A railgun is an electrical gun that accelerates a conductive projectile along a pair ofmetal rails

The projectile is in contact with the two rails and a current passes through theprojectile. This current interacts with the strong magnetic fields generated by the railsand this accelerates the projectile.

Heart Valve SimulationIncompressible CFD Solver in LS-DYNA

Incompressible CFD (ICFD) solver

Author: Facundo Del Pin, LSTC - [email protected]

Incompressible flows cover a vast number of engineering problems ranging from caraerodynamics to arterial flows and parachute simulation.

LS-DYNA offers users two options to doCFD depending upon the kind of problem

they face. The CESE solver is highlyaccurate CFD solver for compressiblefluids. The ALE solver supports bothcompressible and incompressibletherefore making it the choice for highlytransient problems.

Additionally to improve productivity ofthe solver and to satisfy customerdemands for high performance

computing all the features of the solverwere implemented in parallel. A featureof development is the parallel CFD solvercan be coupled to the parallel solidmechanics solver to do parallel FSI. Inthe same way the coupling may be donein parallel with the thermal solver to doconjugate heat transfer.

With the newly developed features beingreleased, future developments in

planning, as well as those listed above,LS-DYNA's CFD's solver remains the codethat raises the bar for other software.

Among the many features of theIncompressible CFD (ICFD) solver in LS-DYNA is its ability to couple with anysolid model to perform Fluid-Structure

interaction (FSI) analysis using implicitor explicit formulation.

Highly non-linear behavior is supportedby using automatic re-meshingstrategies to maintain element qualitywithin acceptable limits. In this work wewill introduce the additional features forconjugate heat transfer, turbulencemodel, biphasic flow, some new featurein terms of mesh generation likeboundary layer meshing and MPP

SGI Cyclone,LS-DYNA and Takata

A User Success Story

Submitted by: Tony DeVarcoSGI Cyclone Program Manager

[email protected] tel: 510-933-5124

Organizations that rely on HPCresources are increasinglyinvestigating cloud computing as asolution that offers additionalcomputing capacity and flexibility.Clouds reduce or eliminate altogetherthe need to make incremental long-term, often costly hardware andinfrastructure investments. To date,cloud solutions have been primarilyfocused on running importantbusiness applications like CRM, ERP,HR, email and other database

programs not technical andengineering applications.

So when SGI began to design ourHPC cloud solution we were razorfocused on the need to offer ourcustomers the scientific andengineering applications that theycurrently use to drive innovation andcreate new products. SGI Cyclone

presently offers end users a selectionof over 20 technical open source and3 rd party ISV applications includingLS-DYNA.

In February, when we launched theCyclone offering, we made availabletwo service models for ourcustomers: Software as a Service

(SaaS) and Infrastructure as aService (IaaS). LSTC was one of thefirst ISVs to sign up for the SGICyclone SaaS offering allowing our

joint customers to purchase from SGIadditional licenses to run their LS-DYNA simulations in Cyclone ondemand.

LSTC and SGI have had a longhistory of working together. It wasnatural that we would partnertogether to deliver LS-DYNA, as a

software service in the cloud, saidJohn O. Hallquist, President,LSTC. SGI offers a team of technicalapplication engineering experts, whofor years have supported theoptimization and benchmarking of oursoftware on their supercomputinghardware architectures.

When our customer Takataapproached us with an urgent need toquickly run 100s of simulations undera very tight deadline we urged themto get in touch with the Cyclone teamat SGI said Marsha Victory,Administrator Global Sales.

Takata Corporation:

Established: 1933

Business:Manufacture and sale of motorvehicle seat belts, airbags,steering wheels, electronicmodules, interior trim,industrial textiles and childrestraint systems.

Employees: 31,154 as of March 2010

Worldwide plants:45 plants in 16 countries as ofMarch 2010

When Takata contacted SGI it wasthe Thursday before the 4 th of Julyholiday weekend. They had 100s ofsimulations that typically ran for 4hours on 4 cores each. We askedwhen they needed to have theirresults back and were told byTuesday July 5 th ! In consultationwith a SGI LS-DYNA applications

expert we jointly came to theconclusion that by deploying a 512core SGI Altix ICE integratedblade cluster we could execute on theproject in less than 48 hours. In orderto expedite the process we had thecustomer upload their files intoCyclone and had our LS-DYNAapplication engineer set up the batchscheduling and launch the jobs.Starting Friday night, the simulationsran for the next 31 hours and weremade available for the customer todownload back to their office onMonday July 4 th ahead of theirdeadline.

From the moment we started talkingwith the SGI Cyclone team I feltconfident that we were going to hitour deadline goal, said Dan Long,Program Manager, Takata, We were

assigned a technical and accountmanager who walked us through theprocess, quickly got us a Statementof Work that outlined the pricingterms and service level agreementand were asked which LS-DYNAversion we currently used in house sothey could have the exact versionready to go on the SGI Altix ICEsystem. Our experience with the SGICyclone team was one of technicalcompetence and efficiency. In fact,we were so pleased with their servicewe have returned to use Cycloneseveral times since our early Julyproject.

SGIs experience with Takata hasbrought home the fact that it takesmore than just fast computers andstorage to run a successful HPC cloud

service. It also takes passionateaccount management and deeptechnical application expertise toprovide our customers with the truevalue they are looking for. This hasgot us thinking that there is an evenhigher value service model we canoffer our LS-DYNA customers viaCyclone and that is what we arecalling Expertise as a Service (EaaS).So if you are looking for a quick andefficient computing environment torun your LS-DYNA simulations pleasegive us a call or send us an email. Welook forward to the opportunity towork with you as a trusted partner.

Isogeometric Analysis 2011www.ices.utexas.edu/iga

January 13-15, 2011, Austin TexasIntegrating Design and Analysis

Dr. David [email protected]

Contact: Ruth Hengst - e-mail [email protected]

Geometry is the foundation ofanalysis yet modern methods ofcomputational geometry have untilrecently had very little impact onanalysis. The reason may be thatFinite Element Analysis (FEA), as weknow it today, was developed in the1950s and 1960s, before the adventand widespread use of ComputerAided Geometric Design (CAGD),which occurred in the 1970s and1980s. The CAGD FEA interfacegives rise to many problems.

Perhaps the most significant of all isthe problem of translating CAGD filesinto analysis-suitable FEA geometryand meshing, reputed to take 80% ofoverall analysis time for complex

engineering designs. Theapproximate, polynomial-basedgeometry of FEA also createsdifficulties in modeling sliding contact,flows about aerodynamic shapes,buckling of thin shells, etc. It wouldseem that it is time to look at morepowerful descriptions of geometry toprovide a new and more efficientbasis for analysis. An attempt toaddress these issues and improve onFEA has led to the introduction anddevelopment of IsogeometricAnalysis, in which a single geometricrepresentation is utilized for designand analysis. Among the approachesthat have been proposed, those that

have demonstrated the mostpotential so far are SubdivisionSurfaces, NURBS, and T-Splines.NURBS are the industry standard forCAGD systems used in engineeringdesign. NURBS-based isogeometricanalysis has already been applied tofluids, structures, fluid-structureinteraction, phase-field modeling,electromagnetics, shape and topologyoptimization, material modeling (e.g.,implicit gradient damage models),discrete and diffuse modeling of crackpropagation, etc. T-Splines, which area generalization of NURBS that allowefficient local refinement whilemaintaining higher-order continuityand exact geometry, have recentlyattracted increasing attention. Thepurpose of this workshop is to bringtogether experts in geometry andanalysis interested in thedevelopment of the new generation ofanalysis procedures based on modernmethods of computational geometry.The workshop will focus on:

Analysis-suitable geometry Mathematics of isogeometric

methods

Impact and Fracture Mechanics Assessment of a Fused Silica Windowhttp://www.predictiveengineering.com/consulting/projects/lsdyna/fused_silica/index.html

Full Graphics can be viewed on the website of Predictive Engineering

Objective:

Determine the survival probability of afused silica window subjected to a largeparticle impact event within a hypersonicwind tunnel using numerical methods(LS-DYNA) and fracture mechanicstheories for brittle solids. If damage ispredicted, provide an assessment of thewindows service life under repetitive

pressure cycling of 14 psi.

Modeling Assumptions and Details:

A finite element (FE) solid model of a 18diameter, 1.5 thick disk was constructedbased on information provided by theengineering team at Arnolds AFB (seeAppendix). The FE model idealized afused silica window that was potted intoa steel frame using Ultracal 60 cement.The window is subjected to a differentialpressure of 14 psi during hypersonicwind tunnel operation. This pressuretends to bow the window outward intothe wind tunnel (internal side).

It is hypothesized that there exists apotential, during a specific wind tunnel

test, for large particle debris(Pyroceram) to impact the window athigh velocities (12.27 ft/s tangential and10.18 ft/s normal to the window). Anominal particle size was determined(see Appendix) and idealized as a spherewith a diameter of 42.90 mm.

Mechanical property data for fused silicaand Pyroceram 9606 is presented in the

Appendix. It should also be noted thatthe mechanical properties for fused silicaare similar at 25 and 176C. Data forPyroceram 9606 at 176 C was notavailable but is believed to follow asimilar trend as that for fused silica.

The analysis approach consists of modelvalidation, impact simulation andinterpretation of the results usingfracture mechanics for brittle solids.Auxiliary static stress models are alsoused to provide additional substantiationof the fracture mechanics predictions.The FE model was built using Femapv10.02 and statically analyzed using NXNastran v6.1. The transient dynamicimpact analyses were performed using

LS-DYNA v971 R4.2 for the Win64platform.

Summary:

(i) Determine stress state in the fused

silica window during and subsequent tothe impact event using LS-DYNA. A LS-DYNA model was constructed of theimpact event using two simulatedparticle sizes (42.90 mm (nominal size)and 12.7 mm). Stresses were calculatedduring and subsequent to the impactevent. Impact stresses were found to behighly localized and the overall stressstate of the window remains unchanged

during and following impact. This resultindicates that the particle can hitanywhere on the window and haveapproximately the same impact response(i.e., impact force on window and stressstate within the window). Since fractureis dominantly initiated by tensilestresses, the following key results weredetermined: (a) the steady-state tensilestress in the window is ~4.0 MPa (580psi); (b) the nominal particle created apeak tensile stress of ~17 MPa (2,466psi) and the smaller particle created apeak tensile stress of ~6.3 MPa (910psi).

(ii) Evaluate the window for itstoughness or resistance to impactdamage based on standard fracturemechanics principles.Results from the LS-DYNA model show

impact forces of 9,400 N (2,113 lbf) forthe nominal particle size (42.90 mmdiameter) and 1,060 N (238.3 lbf) forthe smaller particle of 12.7 mm. Crackformation on the surface of the windowis a function of impact force andsharpness of the contacting particle. Aconservative approach was chosen forthis analysis where the particle was

assumed to be spherical and thereforepresents a smooth contacting surfaceagainst the window. This allows a directcorrelation with experimental fracturemechanics work conducted on fusedsilica where a spherical indenter having a

diameter of12.7 mm was pressed againsta fused silica plate. In this experimentalwork, small surface cracks were noted atloads greater than 600 N (134.9 lbf).Since the smaller spherical particle isshown to cause surface cracking on thewindow, fracture mechanics principleswould then predict that for sharperparticles the probability of surfacecracking is even greater. Moreover, as

the particles become larger (42.90 mm),the probability of crack formation wouldlikewise scale. This allows one toconclusively state that if particlesbetween the sizes of 12.7 to 42.90 mmimpact the fused silica window at thestated velocities, surface cracking willappear on the window.

(iii) Provide an engineering assessmentof the probability of the window survivingthe impact event and if damaged, thelargest flaw it could withstand andmaintain its structural integrity Adetailed FEA contact model of thesphere/window system was created todetermine the contact stresses due tothe particle debris impact.The load for this model was themaximum contact force of 9,400 N(2,113 lbf). Stress results from this

model were then used to drive thefracture mechanics calculations. In thiswork, it was argued that a crack of 5.7mm (0.226) deep would form during theimpact event. Given a fused silicafracture toughness of 0.75 Mpa*m^0.5,calculations show that the window is ableto withstand this flaw size and remainstable. That is, the catastrophic flaw size

47

for the window under a differentialpressure of 14 psi is 8.4 mm (0.331).Therefore, the window should not failduring impact from Pyroceram debris.

The probability of window failure during

the impact event is based on engineering judgment since no direct calculationsexist. In this work, the worst possibleparticle configuration was assumed, thatis, spherical. This assumption providesthe absolute maximum impact force.From this analysis, the impact event waspredicted to create a 5.74 mm deepcrack. However, the propagation of thiscrack into the window for catastrophic

failure is driven by the windows steady-state tensile stress field due to thedifferential pressure load and isdecoupled from the impact event. Hence,if the particle hits away from the centerof the window (i.e., outer radial impact),

the impact induced crack will be morestable (lower tensile stress in thewindow) and less likely to cause failureof the window. Overall, given theconservative nature of this analysis andthat the particle would have to hit near

the center of the window, the probabilityof the window failing in a catastrophicmanner is highly unlikely.

Long term stability of the window isdifficult to predict since fused silica(glass) will tend to weaken due tomoisture exposure. If the wind tunnelremains a dry environment then theimpact induced crack should remain

stable and not propagate during windtunnel pressure cycling. It should benoted that the tolerable crack size is 8.4mm (0.331) and visual inspectionshould be able to detect a crack that islarger than 1/4 of an inch
