摘要:
为了求解半空间内含有部分脱胶的椭圆夹杂与圆形夹杂对SH波的散射影响问题,本文将复变函数法、Green函数法与保角映射技术相结合,根据保角映射的原理,将椭圆夹杂映射为圆夹杂,求出散射波的位移及应力场。结合Green函数法在脱胶部分"虚设点源",根据椭圆夹杂以及圆形夹杂周围应力及位移连续的边界条件,求出位移及应力的基本解。在脱胶部分通过施加大小相等、方向相反的力构造"脱胶模型",得到在半空间内含有部分脱胶的椭圆夹杂以及圆形夹杂对SH波散射的总位移场。通过数值算例表明:得到不同的介质参数对动应力集中系数的影响不同,其中,SH波入射的角度、入射频率、波数比、介质参数、埋深、缺陷之间距离、脱胶角度等对动应力集中系数都有影响。
