摘要

采用“镜像法”和“剖分—契合”思想,对SH波作用下半空间双相介质水平界面上圆形孔洞的动应力问题进行了研究,给出了该问题的解析解和孔边动应力分布规律。分析结果表明:适当避开较大的波数比、较高的入射波波数与垂直入射的同时出现,可达到降低孔边动应力的目的。

Abstract

The analytic solutions and distribution law for dynamic stress of interface circular cavity in bi-material vertical half-space on SH wave were obtained using the methods of image and ideas of partitioning –conjunction. The analysis results demonstrate that the purpose of reducing hole edge dynamic stress can be achieved by properly avoiding the large wave number, high incident wave number and SH-waves incident in vertical angle appear simultaneously.
