Abstract

The whole process of shaped charge jet penetration into concrete was simulated using Ansys/LS-DYNA.The results of simulation were identical with the experiments.The influences of the angle of the liner,the thickness of the liner,the thickness of the cover,standoff,and the length of the charge were analyzed.The results indicated that the angle of the liner,the thickness of the liner and the standoff is more important to the efficiency of the shaped charge jet than the thickness of the cover and the length of the charge.
