In this paper we extend the application of the sequential Dirichlet-Neumann iterative boundary element-
finite element coupling method to elasto-plasticity. The successive computation of the displacements and
forces/tractions on the interface of the finite element and boundary element sub-domains is performed
through an iterative procedure. The procedure is implemented in a computer program and is tested through
linear elastic fracture mechanics and elasto-plastic fracture mechanics problems.
Keywords: Boundary Element Method; Finite Element Method; Elasto-Plasticity; Fracture Mechanics,
Iterative Methods; Coupling.
1 Introduction
For certain categories of problems, neither the boundary
element method (BEM) nor the finite element method
(FEM) is best suited and it is natural to attempt to couple
these two methods in an effort to create a finite element-
boundary element method (FEBEM) that combines all their
advantages and reduces their disadvantages.
