Abstract

Deformation-timecurvesofsheetmetalpenetratedbythepolycarbonate(PC)projectiles withdifferentnoseshapeswereexperimentallyobtainedaswellastheprojectile-targetinteraction timesbyusinganair-jetloadingapparatus.ThefailurecharacteristicsofthePCprojectilesduring penetrationwereobserved,whichincludingfracture,initialdamageandnoseplasticdeformation.The deformationsofthetruncated-cone-tipPCprojectilesafterpenetrationwereanalyzedbyaphotoplastic method.AndtheDSGZconstitutivemodelwereembeddedintothefiniteelementcodeasausersubroutinetonumericallysimulatethepenetrationprocessofth PCprojectilesintothealuminiumtargets. Thesimulatedresultsareinagreementwiththeexperimentalones.
