# Engineering Analysis of Penetration of a Metal Ball Into Fibre-Reinforced Composite Targets

• An engineering analysis method of computing the penetration problem of a steel ball penetrating into fibre-reinforced composite targets is presented. The metal ball was assumed to be a rigid body, and the composite target was regarded as a transversely isotropic elasto-plastic material. In the analysis, the spherical cavity dilatation model is coupled with the cylindrical cavity penetration method. The simulation results based on the modified model are in good agreement with the results for the 3D Kevlar woven composite (3DKW) antipenetration experiments. Furthermore, the effects of the target material parameters and impact parameters on the penetration problem were also studied.
