摘要
"破坏波"(failure wave)的研究始于1991年RASORENOV等首次报道的在冲击加载应力低于或接近Hugoniot弹性极限(σHEL)时,在K19玻璃样品的自由面速度历程上观测到的反常的再压缩信号。它是指在冲击波极端条件下,玻璃、陶瓷等脆性材料中的独特的压缩破坏现象。较为全面地回顾综述了在冲击压缩作用下脆性材料中破坏波的力学物理特性和形成机制,介绍了这方面的研究工作和取得的阶段性结果。
The study of the failure wave originated in 1991when Rasorenov reported that a small and abnormal recompression signal in their recording of the free surface velocity is taken in K19 glass when the shock stress is below or close to the Hugoniot Elastic Limit （crHEL）. A comprehensive review and comment on the studies of the physical properties and possible formation mechanisms of the failure wave in brittle materials under shock compression were given. The research and work done in this area was also presented.
