摘要

本文研究了半圆柱形峡谷中各向异性(正交异性)半空间中sh波的散射问题。采用复变函数法和多极坐标系求解动应力集中问题。根据包裹体与峡谷的边界条件，计算并讨论了包裹体周围动应力集中系数的算例。数值计算结果表明，动应力集中系数主要受波数、包裹体深度以及包裹体与峡谷半径比的影响。

Dynamic stress concentration factor around inclusion in anisotropic half-space with a semi-cylindrical canyon

Scattering problem of SH-waves in anisotropic (orthotropic) half-space with a semi-cylindrical canyon is researched in the present paper. Complex function method and multi-polar coordinate system are adopted to solve the problem of dynamic stress concentration. According to the boundary condition of the inclusion and the canyon, some examples about dynamic stress concentration factor around the inclusion are calculated and discussed. Numerical results present that the dynamic stress concentration factor is mainly affected by the wave number, the depth of the inclusion and the radius ratio of the inclusion and the canyon.
