Abstract

Atwo-dimensionalLagrangianelastic-plastichydrodynamicfiniteelementcodenamedLTZ- 2Dwasusedtonumericallyexploretheinfluencesoftheaggregatestructuresonthepenetration processesoftheconcretetargetsimpactedbytheprojectilesaswellasthecorrespondingtargetdamage. Andthedimensionsoftheaggregatestructureswereconsideredtobemuchlessthanthoseofthe projectiles.Comparedwithevenconcretetargets,forathinaggregateconcreteplate,whentheimpactvelocityisrelativelylow, theaggregatestructurewillresisttheprojectile,butwhentheimpact velocityishighenough,theresidualvelocitywillbehigherduetothedamageareaincreaseintheback oftheconcreteplate.However,forthickconcretetargets,theinfluencesoftheaggregatestructures onthepenetratingprocesscanbeignored.
