An engineering analysis of penetration of metal ball into fibre-reinforced composite targets

【摘要】 An engineering analysis of computing the penetration problem of a steel ball penetrating into fibre-reinforced composite targets is presented.Assume the metal ball is a rigid body,and the composite target is a transversely isotropic elasto-plastic material.In the analysis,a spherical cavity dilatation model is incorporated in the cylindrical cavity penetration method.Simulation results based on the modified model are in good agreement with the results for 3-D Kevlar woven(3DKW) composite anti-penetration experiments.Effects of the target material parameters and impact parameters on the penetration problem are also studied.更多还原
