Abstract

In order to analyze penetration of three types of shaped charge jet in moving oblique target,the ANSYS / LS-DYNA software was used to build armor warhead's model. By a series of numerical simulation,the results show that the JET penetrated obviously into moving oblique target but could not guarantee the stability,the EFP cratered obviously on it but could not penetrate through it,JPC penetrated obviously it and could guarantee the stability. In conclusion,the penetration of JPC is better than the other two types of shaped charge jet in moving oblique target.
