Abstract
An analytical model of ceramic target against shaped charge jet penetration is presented in this paper. The model in which damage is considered is developed by the spherical cavity expansion theory. The experiment of jet penetration into ceramic is analysed using the model in this paper. The theoretical results show good consistence with the experimental results. Numerical simulation of jet penetration into ceramic is presented, and the influence of parameters of liner on the penetration depth is discussed. It indicates that the influence of liner thickness on the penetration depth increases with liner angle and that the influence of liner angle on the penetration depth increases with liner thickness. The simulated results of penetration velocity consist with the theoretical results. It shows that the model presented in this paper is feasible.
