Theoretical model and numerical simulation of ceramic target against shaped charge jet penetration

摘要

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