Before I starton that, Iwant tomentionfourmechanicianswhohavehadanenormousinfluenceonmyprofessionallifeaswellashavinggreatlyenrichedmypersonallife:JohnHutchinson,ViggoTvergaard,JimRiceandErikvanderGiessen.Thereisnotenoughtimetodetailmydebttothem.My life inmechanics beganmy senior year at theUniversity of Pennsylvania. I took a course incontinuummechanics from Hsuan Yeh whowas Dean of the Towne School. The course was sointerestingthat IdecidedthatwaswhatIwantedtostudy ingraduateschool. IwenttograduateschoolatHarvardandwasveryluckythatayoungfacultymembernamedJohnHutchinsonagreedtobemy thesisadviser.MyPhD thesis involved the finite strain, finiteelementanalysisofa twodimensionalperiodicarrayofcircularholes(motivatedbythepioneeringductilefracturestudiesofFrank McClintock and Jim Rice). This initiated me into two emerging developments in solidmechanics: finiteelementmethodsandmaterialsmechanics.As JohnHutchinsonremarkedinhisTimoshenkoMedaladdress,wedidnotrealizewewereparticipatinginarevolution.At that time finite element methods were not well regarded by much of the solid mechanicscommunity.Toomanyyearspassedbeforecomputationalmechanicswasacceptedandintegratedintomainstreamsolidmechanics.IampleasedthatthesituationisverydifferentnowasevidencedbytheTimoshenkoMedalhavingbeenawardedtoOlegZienkiewicz,TinsleyOden,TedBelytschkoand Tom Hughes. Materials mechanics was more readily accepted and became a source ofwonderfully challengingproblems. It has stimulated thedevelopmentof newmechanics theoriesandexperimentalmethods,particularlythoseaimedatunderstandingsmallsizescalephenomena.Conversely, it has led to solid mechanics having a significant impact on materials science andengineering.

I thought it would be fun to do the bifurcation analysis andcalculatethesubsequentneckdevelopmentusingfiniteelements.ThatworkedoutwellandIwasaskedtogiveaseminaronthisworkbyHarveyGreenspan,thentheheadofAppliedMath.Hegaveme some sage advice “No one every complained that a lecturewas too short.” I have tried, notalwayssuccessfully,tofollowhisadvice.Thetitleofmytalkwas“NeckinginBars.”Tothebestofmyknowledgeit istheonlyMITAppliedMathtalkeverlistedintheentertainmentsectionofthelocalpaper.MidwaythroughmystayatMITIhadaleaveofabsenceattheTechnicalUniversityofDenmarkandbeganmycollaborationwithViggoTvergaard. ViggoandIworkedonbucklingandwhenIcame

back from Denmark I got excited about a plastic buckling issue. My idea was that the so‐calledplasticbucklingparadoxcouldberesolvedbyconsidering threedimensionaleffects. ImentionedmyideatoJohnHutchinsonwhoknewIwasclearlywrongbutdidn'ttrytodampenmyenthusiasm.I am grateful for that. Eventually I realized I was wrong, learned how to differentiate betweenexcitementandinsight,andtoacceptbeingwrongandthenmoveon.DuringmytimeatMITIwasfreetopursuewhateverexcitedmeandwasabletodevelopmyownresearchstyle.AfterfiveyearsatMITIwastoldmyserviceswerenolongerneededandIwasextremelyfortunatetowindupatBrown.OneareaIworkedonwhenIstartedatBrownwasneckingproblemsrelatedto sheet metal forming. I gave a presentation on some of that work at a Canadian AppliedMechanicsConference.Idon'tremembermytalkbutIdorememberthat,atleastinonerespect,mypresentationwasthehitoftheconference.ThespeakerattheconferencedinnerwastheMinisterofEducationofBritishColumbia.Shebeganherspeechbysayingthatshehadbeenlookingthroughthe book of abstracts during dinner and the titles meant nothing to her until she came across“Necking in Thin Sheets.” That title she could relate to. But she had one question, “Why do thesheetshavetobethin?”Fortunately,Iwassittingtoofarinthebacktobeexpectedtoprovideananswer.Therewas a great deal of intellectual excitement in solidmechanics at Brown in the late 1970s.Much of it stemmed from JimRicewho hadmany original and deep ideas, andwas generous insharing them. One topic was the coupling of grain boundary diffusion and plastic creep inpolycrystallinemetals.Plasticdeformationcouldeffectivelyshortendiffusionlengthssotherecouldbeasynergisticeffect.Quantifyingthisrequirednumericalcalculations.That'swhereIcamein.Thefiniteelementformulationofthisprobleminvolvedcreatingastiffnessmatrixwithsurfacetermsaccountingforgrainboundarydiffusioninadditiontotheusualvolumetricterms.Thecalculationsquantifiedasignificantsynergisticeffect.Years latertheideaofafiniteelementformulationwithseparate constitutive descriptions for volumes and surfaceswas to play a prominent role inmyresearch.In the1960sand70scomputationswerecarriedoutatacentraluniversitycomputercenterandCPUtimewasascarceresource.Programswerewrittenonpunchcardsandsubmittedtocomputeroperatorsoveracounternotunlikethecounteratafastfoodrestaurant.However,theturnaroundtimewasmeasuredinhoursratherthanminutes.Whatcamebackwasastackofpaperthateithercontainederrormessagesoraprintoutofnumbersthathopefullycorrespondedtoameaningfulresult.Draftsmenwereemployedtoturnthenumbersintopictures.Computerterminalsreplacedcardstowardtheendofthisperiodbuttherestoftheprocesswasprettymuchthesame.Ahuge change cameat theendof the70swhen the solidmechanics groupatBrownacquiredadedicated computer for computationalmechanics, aDECVAX780. This acquisition providedmewith a lesson in humility. The DEC salesman mentioned that the standard VAX configurationincludedone67MBytedisk.HeaskedifIwantedtopurchaseaseconddisk.Ianswered“No,we'llneverfillup67MBytes.”TheVAX780consistedofseveralrefrigeratorsizecabinetsandcoulddodoubleprecisionfloatingpointoperationsatabout0.14MFlops.Toputthisinperspectiveitislessthan1/100thespeedofamodernsmartphone.Butwewerethrilledwith itsperformanceand itopenedupnewpossibilitiesforsimulation.Again largely stimulated by Jim Rice's interests, I became involved in research on plastic flowlocalization(aseminalpaperonthattopicwasco‐authoredbyJimandthisyears'DruckerMedalistJohn Rudnicki). The conditions for initiation were established but determining the evolutionrequiredcomputation. ViggowasvisitingBrownandourfirstprojectontheVAXwascalculating

shearbanddevelopmentusingtheJ2‐cornertheorythatJohnHutchinsonandJesChristoffersenhaddeveloped. I found it exciting to be able to simulate the evolution of such complex deformationpatterns. Iwas sopleasedwith the resultingpictures that I broughta reprinthomeandproudlyshowedittoour6and8yearoldchildrensaying“LookwhatIdid.”Oneofthem(Idon'trememberwhich)said“No,youdidn't.You'renotsmartenough.Mommyprobablydidit.”Anotherlessoninhumility.At about the timeViggo and Iweredoingour calculationsBobAsarowas investigating localizeddeformationinsinglecrystalsexperimentally.InworkwithBobandDanPeircewefoundthatrateindependentsinglecrystalcalculationscompletelybrokedownforacertainrangeofparametersofinterest. Eventually we found that accounting for material rate dependence could eliminate thepathological behavior.Ratedependent single crystal calculationswere able to simulate observeddeformationresponsesremarkablywell.An issue with the rate independent localization calculations with Viggo and Bob was that theformulation did not contain a material length scale. The band thickness and hence the post‐localizationresponsewereessentiallydeterminedbythefiniteelementdiscretizationratherthanby any mechanism embedded in the modeling. Material rate dependence in effect led to theintroduction of a length scale. Whether or not this is the governing length scale in a specificsituationisanothermatterbutwefoundthatratedependencecanregularizelocalizationproblems.Iliketothinkthatourcomputationsoflocalizeddeformationmodesplayedaroleinstimulatingatleast some of the subsequent work on incorporating a material length scale into continuumplasticitytheories.Meanwhile JimRice,BenFreundand their collaboratorswere carryingoutpioneering studies infracture mechanics. What got me excited was the possibility of using computation to directlysimulatefracture.ThisledtoaseriesofmicromechanicalfracturestudieswithViggo.Again,akeyissue is how to incorporate a length scale into the formulation. A main aim of the fracturesimulations that Viggo and I (andnowmany others) are engaged in is to relatemeasurable and(hopefully)controllablefeaturesofamaterial'smicrostructuretoitsfractureresistancetoprovideabasisfordesigningmorefractureresistantmaterialsystems.Ratherthanquantitativepredictionsthese simulations seek to provide trends, scaling relations and insight into the mechanismscontrollingtoughnessandductility.ThroughoutmytimeatBrowntherewasawonderfulspiritofcooperationandinteraction.Manyofthe projects Iworked on came from discussions in the hallways or over lunch or coffee. Just tomentiononeexample:myworkoncohesivemodelingstartedafteraninformaltalkSteveNuttgavewhere he showed some pictures of void nucleation at a fiber end in an Al‐SiC composite. ThecombinationofSteve'smicrographsandmyearlierworkwithJimRiceongrainboundarydiffusionledtotheideatoregardacontinuumasconsistingofbothsurfacesandvolumes,withaconstitutiverelationforeach.Hence,aninitialcrackwasnotneededtouseaBarenblatt/Dugdaletypecohesiverelation.Acohesiveframeworkintroducesalengthscaleandcanbeusedtocreatenewfreesurfacethusmodelingcrackinitiation.Thecomputercodefromthegrainboundarydiffusionworkhadtheinfrastructure to implement this. In subsequentwork,withAresRosakis and laterwith YehudaBen‐Zion, we analyzed rupture propagation along surfaces described by frictional constitutiverelationsusingbasicallythesamecomputationalinfrastructure.ThereweregroupgrantsatBrownthatmadeitpossibletoexplorenewareasofresearchwithoutworryingaboutfinancialsupport(ifyouwerenotanexperimentalist).BecauseofthisIwasabletodevelop my collaboration with Erik van der Giessen on discrete dislocation plasticity. Discrete

dislocationplasticityalsointroducesalengthscale(infactseverallengthscales).Sonowinsteadofno length scale, identifying the governing length scale in a problem can be an issue. One ofmyfavoriteprojects in thisareawasourworkwithVikramDeshpandeon fatiguecrackgrowth thatgaveafatiguethresholdandaParis lawasnaturaloutcomesofthesimulations.Anotherwasourworkwith LuciaNicola and JoostVlassak ofHarvardwhich involved a direct comparison of oursimulationsforstressevolutioninthinfilmswithJoost'sexperiments.Quitegenerally,IregardwhatIdoassolidmechanicssimulation:anidealizedmodeliscreatedthatis governed by the equations of mechanics which are then solved computationally. Suchsimulationscanbeapowerfultoolforgaininginsightintofeaturesthatarenotdirectlyaccessibleexperimentally. Comparison of predicted observables with experiment is a win‐win situation:agreement gives confidence in the predictions while disagreement can point the way to thedevelopment of improved theories and models. Another role for such simulations is to identifyregionsofparameterspacethatmeritexperimentalexploration.Ifinditgratifyingthatthisactuallyhappened in work with Ares and Demir Coker. What has typically been missing from solidmechanics simulations is a statistical perspective. I will venture a prediction that a statisticalperspectivewillbecomemoreprevalentinthefuture.OvermyyearsatBrownIbenefitedenormouslyfromcollaborationswithmanypeopleinadditionto those named already. There isn't time to name them all but I will mention a sampling:extraordinary colleagues includingFong Shih, Subra Suresh,MichaelOrtiz,K.S.Kim,BenFreund,RodCliftonandBillCurtin;wonderfulcollaboratorsfromaroundtheworldincludingYvesBréchet,MortGurtin,NormanFleck,XavierOliverandRenédeBorst;andanexcellentgroupofstudentsandpost‐doc visitors including Nick Triantafyllidis, Rich Becker, Xiaopeng Xu, Amine Benzerga andAlfredoHuespe.IretiredfromBrownafterbeingafacultymemberfor34yearstobeclosertograndchildren.Iwasvery fortunate to get a position in the University of North Texas (UNT) Materials Science andEngineeringDepartmentwhich is in anexciting stageofdevelopment.
