摘要: 通过研究柔性防护和刚性防护方面的实例，结合作者的研究结果，对应力波效应和材料动态特性效应如何影响强动载荷下的结构安全防护进行了分析和讨论。研究表明，在研究强动载荷下的结构安全防护时，不论结构承受的是爆炸冲击波还是弹体的直接撞击，都应该考虑结构与周围介质中的波传播效应与材料的应变率效应，以及这两者之间的互相联系和互相耦合。

Abstract: Some examples of both flexible protection and stiff protection were discussed in connection with the authors research results to explore influences of stress wave effects and material strain-rate effects on structure safety protection under intense dynamic loads. Results display that in studies on structure safety protection under intense dynamic loading, either the loading is due to shock waves or projectile impact, wave propagation effects and material strain-rate effects for the structure itself and the around media, as well as the interaction between them, should be taken into account.
