In hypervelocity impact problems, it is difficult to accurately obtain the crater morphology under certain conditions. Studying the damage zone can compensate for this limitation and serve as an important basis for understanding the impact mechanism and validating numerical simulations. However, there has been limited research on numerical simulation of the damage zone due to the lack of experimentally validated criteria. This paper presents a summary of the existing quantitative measurement results for the damage zone. The findings reveal that, for the same target, the depths of the damage zone obtained through multiple microscopic testing methods are relatively consistent, which facilitates the analysis of the damage zone. Based on the iSALE code, the applicability of total plastic strain (TPS), damage factor (D), and peak pressure as criteria for assessing the damage zone is analyzed. The results indicate that, TPS=0.1 is appropriate as a damage criterion, D=1 could be used as a damage criterion with caution, while peak pressure is not a suitable damage criterion. Through parametric analysis, it is found that the damage zone gradually decreases with increasing porosity and target strength.

超高速撞击问题中,靶体损伤区研究能够弥补部分实验中难以精确获取成坑形貌的问题,为撞击机理研究和数值模拟的校验提供重要依据. 损伤区的数值模拟研究开展较少,主要原因是缺乏经过实验验证的损伤区判据. 本文总结了已有的损伤区定量测量实验结果,发现对于同一种靶体,多种切片显微测试方法得到的损伤区深度比较吻合,这给损伤区分析提供了便利. 基于iSALE程序模拟分析了累计塑性应变、损伤因子和峰值压力作为损伤区判断参数的适用性,认为TPS=0.1适合作为损伤判据;D=1可以作为损伤判据,但误差较大需谨慎使用;峰值压力不适合作为损伤判据. 通过参数化分析发现,随着孔隙率增大和靶体强度增大,损伤区深度逐渐减小.
