Abstract

In this paper, adopted explicit dynamic analyzing program AUTODYN basing on finite element to simulate the process of the shaped charge jet formation and the penetration through the steel target, base on the characteristic of the shaped charge structure and the mechanisms of jet penetrating the target. Adopted ALE ( Arbitrary Lagrange Euler ) arithmetic to acquire numerical simulation results. By analyzing, the simulation result that the shaped charge jet formation is basically accordant by contrasting the physical phenomenon and rule. At one time,the result that the target be damaged is basically same by contrasting the result of the trial. The simulation model and method that the shaped charge jet formation and the penetration through the target are proved to be reasonable and feasible. Keywordsthe shaped charge; jet; numerical simulation
