Diffraction of SH Waves by an Elliptic Inclusion with Partially Debonded Region in Bi-Material Half Space

Base on elastodynamics, complex function method with mapping function and Green's function method are used to investigate the scattering of SH waves by an elliptic inclusion with a partially debonded region. The bi-material half space is divided into two parts along the vertical interface to investigate the two right angle plane respectively. Secondly, "image" method and conformal mapping method are employed to construct the scattering wave field in part I. Then the Green's function needed is obtained. Thirdly, with the aid of interface "conjunction" technique, a series of integral equations for determining the unknown force system could be set up through continuity conditions on the interface and Green's function. The method presented in this paper can be used to solve other similar scattering problem by arbitrary shape inclusion with partially debonded region.
