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

Abstract

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.
