Abstract

Copperparticleimpactbehaviorsincoldsprayingwerenumericallysimulatedbyusingthe LS-DYNAprogram.Someimportantaspectsonthe3Dmodelingwereexamined.Effectsofthemeshingsizeonparticlecriticalvelocityandparticledeformationwerealsoinvestigated. Theresultsshow thatthecontoursofthedeformedparticleobtainedbythe3Dmodelaremorecomparabletotheexperimentalobservationthantheprevious2Dsimulate results.Thedistortionofthesolidelementatthe contactzoneinthe3Dmodelismuchweakerthanthesurfaceelementusedinthe2D model.Therefore, nosteepincreaseofeffectiveplasticstrainofelementscanbeobservedduringtheimpact process.Furthermore,themeshingsizealsotakesanimportantroleinthe3Dsimulatedresults.The criticalvelocity,flatteningratioandcompressionratioobtainedbyextrapolationmethodsareingood agreementwiththeexperimentalresults.
