Abstract

An overlapping iterative domain decomposition algorithm for coupling the finite element method (FEM) and the boundary element method (BEM) is presented in this paper. In this proposed method, the domain of the original problem is subdivided into a FEM sub-domain and a BEM sub-domain, such that the two sub-domains partially overlap over a common region. The method is most suitable for the elastoplastic analysis of infinite and semi-infinite problems. It handles situations where the natural boundary conditions are specified on the entire external boundary of the FEM or BEM sub-domains. Such situations cannot be modeled using the existing non-overlapping iterative coupling methods. The method is implemented in a computer program, which is tested through numerical examples. The solution of the present method is compared to the conventional finite element method in terms of accuracy and CPU-time.
