Abstract

The pressure and temperature increase resulting from the impact of different threats onto target materials is analyzed with a unified laboratory-scale setup. This allows deriving qualitative information on the occurring phenomenology as well as quantitative statements about the relative effects sizes as a function of target material and threat. The considered target materials are steel, aluminum, and magnesium. As threats, kinetic energy penetrator, explosively formed projectile, and shaped charge jet are used. For the investigated combinations, the measured overpressures vary by a factor of up to 5 for a variation of the material, by a factor of up to 7 for a variation of the threat, and by a factor larger than 15 for a simultaneous variation of both. The obtained results as well as the experimental approach are relevant for the basic understanding of impact effects and risks due to material reactivity. The paper combines two main aims. Firstly, to provide a summary of own prior work in a coherent journal article and, secondly, to review and discuss these earlier results with a new perspective.

压力和温度对不同反应性材料的影响

通过统一的实验室规模设置，分析了不同威胁对目标材料的影响所导致的压力和温度升高。这样就可以得到关于发生现象的定性信息，以及关于作为目标材料和威胁函数的相对影响大小的定量陈述。考虑的目标材料是钢、铝和镁。作为威胁，采用动能穿甲弹、爆炸成形弹和聚能射流。对于所研究的组合，测量的超压随材料的变化而变化，最大可达5倍；随威胁的变化而变化，最大可达7倍；如果两者同时变化，最大可达15倍。得到的结果以及实验方法与基本理解材料反应性的冲击效应和风险有关。这篇论文有两个主要目的。首先，在一篇连贯的期刊文章中提供自己先前工作的总结，其次，以新的视角回顾和讨论这些早期的结果。
