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

Department of Modern Mechanics, University of Science and Technology of China, Hefei 230027, P. R. China

摘要

摘要: 介绍了钢球贯穿纤维增强复合材料靶板的一维工程近似分析方法．钢球被假定为刚体，复合材料靶被近似为横观各向同性弹塑性材料．通过将球腔膨胀模型和柱腔贯穿相结合的方法，提出了一种改进的复合材料靶抗贯穿的工程近似分析方法．利用该方法，对三维芳纶纤维编织(3DKW)复合材料靶板开展了抗钢球贯穿的工程近似分析，计算结果与实验结果一致性较好；并进一步讨论了计算中材料主要参数对靶板抗贯穿规律的影响．

Abstract: 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.
