本文描述了爆炸冲击硬化对高导无氧铜和工业纯铁一类高应变率机械材料性能的影响．这些有延伸性能的材料，以及那些作为标准的材料被用于模拟设计典型的爆炸成形弹丸（ＥＦＰ），其结果与实验得到的ＥＦＰ的Ｘ光照片相比较．对标准的或冲击硬化后的材料，导出的流动应力／应交关系都不能成功模拟ＥＦＰ．而冲击硬化材料的流动应力特性与现有材料的基本模型普遍是不符合的。以冲击硬化材料屈服应力和现有铁和铜的基本模型的观测趋势为基础，应用工作硬化的药形罩简单流动应力模型，发现ＥＦＰ编码模拟与实验是很一致的。
This article describes the impact of impact hardening on the properties of high strain rate mechanical materials such as high conductivity oxygen free copper and industrial pure iron. These extensible materials, as well as those used as standard materials, were used to simulate the design of a typical explosion projectile (EFP) shot and the results were compared with the X-ray photographs of the experimentally obtained EFP. For standard or impact hardened materials, the derived flow stress / relationship can not be successfully simulated EFP. However, the flow stress characteristics of impact hardened materials are generally not consistent with the basic models of existing materials. Based on the observation trend of the yield stress of impact hardened material and the basic model of existing iron and copper, a simple flow stress model of working hardened apron was used and it was found that the EFP coding simulation was in good agreement with the experiment.
