Abstract

Abstract: In this paper, the method of fundamental solutions (MFS) is applied in combination with the domain decomposition method to the simulation of elastic wave propagation in layered materials. The domain of the problem under consideration is decomposed into several sub-domains. In each sub-domain, the solution is approximated separately by the MFS formulation. At the sub-domain interfaces, continuity of the displacement and traction is imposed as the boundary conditions. The validity of this approach is demonstrated through a series of two- and three-dimensional numerical experiments.
