Abstract
This paper presents a method for the coupling of the finite element method
(FEM) and the boundary element method (BEM) for 2-dimensional stress analysis
problems, which allows for the modelling of body forces. The structural system
of equations is based on boundary element format and the transformation of finite
element equations of the FEM subregion into BEM format is limited to the
interface nodes. The modelling of smooth and non-smooth FEM/BEM-interfaces
and the associated difficulties are described in detail.
1 Introduction
Most work on the coupling of the FEM and the BEM relies on the use of
equivalent BEM-stiffness matrices, which have the disadvantage that a full
inversion of the traction matrix is required/ The coupling method
presented in this paper relies on the transformation of the FEM format of
the interface degr
