Abstract
A new type of boundary element program is presented. The equations are derived by use of integral operators. A natural way of deducing element matrices in BEM is shown, which leads to a new technique for establishing the system of equations. A simple subsidiary condition technique, which makes it possible to take discontinous tractions into account, is presented. Guidelines are given for the BE-discretization and the numerical integration. Formulas for the analytical integration of the singular terms are shown. A non-conventional method for coupling BEM and FEM is proposed. Numerical studies have been made in order to investigate the performance of different elements.
