Subregion Boundary Element Method

Abstract

This paper concerns a new boundary element analysis approach for the object divided into subregions. In this approach, the system of equations for each subregion, which is derived from the boundary integral equation, is transformed to an equation similar to the stiffness equation of the finite element method (FEM). The global equation is made by the superposition of these matrix equations. The present approach is derived theoretically and is compared with the existing ones in order to indicate its features. Then, it will be applied to analysis of two-dimensional elastic and potential problems.
