Finite element simulation using LS-DYNA3D has been performed to describe the physical and mechanical course of penetration to ceramic/Kevlar composite by fragment. Rules of several important parameters are also got, which are compared with those about homogeneous steel targets of the same surface-density. The ceramic/Kevlar composite armor is better than the homogeneous steel target of the same surface-density in ballistic performance.
