Abstract

In this article we present the exact solution of the following canonical problem. We consider the scattering system consisting of a fluid-loaded three-dimensional isotropic elastic halfspace, which is homogeneous except for the presence of a finite flat crack. The crack breaks the surface of the halfspace, and in the current formulation is taken to be orientated normal to the halfspace surface.
