Abstract:	This paper is concerned with the hybrid method of boundary element and finite element techniques by means of an “external-super-element” function of the commercial finite element method code . The proposed super-element method preserves the modelling simplicity of the boundary element method and the generality of . Two- and three-dimensional elastostatic analyses are performed to demonstrate the accuracy of this method as well as its applicability to practical problems.
