摘要
本文采用自相似方法第一次以封闭形式给出了在匀速扩展剪切载荷作用下1/4空间的动力响应,探讨了冲击波产生和发展的条件,以及在超高速冲击下材料破坏的不同机理。
In this paper, dynamic response ia a quarter space tinder shear load with constant extension has been presented in closed form by means of self-similarity method. The conditions of generation and development of impacting wave and damage of materials under high velocity impact have been discussed.
