Abstract

A new subregion boundary element method will be presented in this paper. In this method, the system of equations for each subregion is transformed into an appropriate form independently. The interface traction matrix equations are generated from these system of equations by using the traction and continuity conditions on the interface between subregions. The displacement components can be obtained once the unknown traction components are solved from the interface traction matrix equations. The present method is more efficient than traditional methods because it significantly reduces the size of the final matrix. Also, as the system of equations for each subregion is solved independently, parallel computing can be utilized, which is advantageous for cases where a large number of elements need to be used, such as in crack analysis.
