Abstract

This paper presents a study of the interaction of embedded flexible inclusions with a multi-layered semi-infinite elastic medium. An infinite boundary element technique is used to model the layered half-space, and employs a decay function representation of the far-field displacements at the free surface and the layer interfaces. The integrals over the far-field are evaluated analytically, resulting in an algorithm which permits rapid computation of the system of equations. A sub- structuring technique is employed to eliminate the interface quantities. Particular attention is necessary to deal with the edge and corner tractions and a novel method of developing the auxiliary equations necessary for this purpose is described in some detail.
