Scattering of plane harmonic SH wave by dipping layers or arbitrary shape

The antiplane strain model for scattering of plane SH waves by dipping layers of arbitrary shape is investigated by using the indirect boundary integral method. The dipping layers are of finite length perfectly bonded together. The material of the layers is assumed to be homogeneous, linearly elastic, and isotropic. Presented numerical results incorporate variation in the number of layers, the angle of incidence, the frequency of the incident wave, the material properties, and the shape of the layers.--Journal abstract.
