Anti-plane Response of a Dike near Bi-material Interface to SH Waves

Abstract

Abstract In the present work, we study the scattering of SH waves by a dike embedded near the interface of bi-material half space. For this, a simple model is utilized to discuss the response of a dike near the interface. Complex function method, image principle, region-matching technique and Green function method are introduced to obtaine the total displacement fields along the free surface of the dike. The results are presented graphically considering the different material parameters. The results show that the displacement along the dike is greatly dependent upon the properties of bi-material interface.
