Abstract:Based on the finite element software LS-DYNA, this paper analyse kinds of shaped charge penetration to concrete. The form of penetrators are depicted together with the penetration, which shows within the same condition of diameter, the one with higher axis can form the rod-shaped penetrator with high velocity, large slenderness and rational mass distribution., bur the effective of caviting is much worse than the other two. And we also obtained the data related of the depth and the cavity radius. Penetration and damage of concrete target simulated agree well with testdata,which indicate that:The simulation in this paper is feasible and reliable.
