Abstract

Athree-dimensionalsmoothedparticlehydrodynamics(SPH)codewasdevelopedtosimulatethepenetrationofceramic/ metalcompositearmorsbyprojectiles.TheJohnson-CookandJohnson- HolmquistIIconstitutivemodelsandtheMie-Grneisenequationofstatewereincorporatedinto thedevelopedcodetodescribethenonlineardeformationanddamagefeaturesofmetalandceramic materials.Thetypicaldisplacement-timecurvescomputedbythedevelopedSPHcodeareingoodagreementwiththeexperimentalresults. Thenumericalsimulationscanrepresentthemajorfeatures ofthecompositearmorsystem suchas,projectileerosion,ceramicconoidformationandsplash, backingplatefailureandsoon.Andtheobliquityeffectsonthepenetration-resistanceabilityofthe compositearmorwereinvestigated.Theresultsindicatethatthereexistsanoptimalobliquityforthe penetration-resistanceability.
