Dynamic analysis of SH wave by a three-layer inclusion near interface in bi-material half space

In this paper, the scattering of SH waves by a three-layer inclusion near the bi-material interface has been studied. A complex function method is employed to solve a two-dimensional wave propagation problem. The displacement fields in the bi-material half space and inside the linings of the inclusi...
