Abstract

A14.5-mmslipchambergunwasusedtoshootthesphericalsteelprojectilewiththediameterof6mmtopenetrateintosteel- aluminumorsteel-aluminum-steelexplosively-weldedplates.The LS-DYNA3Dsoftwarewasappliedtosimulatethesepenetrationprocesses,andthetie-breakmodel wasusedtodescribetheinterfacesbetweentheexplosively-weldedlayers.Theeffectsofthedifferent combinationsoftheexplosively-weldedplatesontheanti-penetrationperformancesandthedamage mechanism wereanalyzed.Theresultsshowthatwhenthetotalthicknessoftheplateisconstant,the anti-penetrationperformanceofthethree-layerplateisbetterthanthatofthetwo-layerplate.Forthe two-layerplate,theoptimizedthicknessratioofthetwolayersisabout2∶1.Atthisratio,thetwolayerplate, ofwhichthefrontlayerissteel,therearlayerisaluminum,hasthebestanti-penetration performance.Thedamagemechanismofthefrontlayerisshearingandtucking.Thedamagemechanismoftherearlayerisprolongingdeformation( whenitisaluminum)andpetaldeformation(when itissteel).Andthesimulatedresultsareingoodagreementwiththeexperimentalones,sothetiebreakmodelcanreflecttheeffectoftheinterlayercombinationonanti- penetrationperformances.
