This paper purports to study the possibility of compounded mesh pattern for evaluating the singularities in three-dimensional dissimilar materials. Because of the plural singularities in those materials, it is generally not easy to make a mesh pattern that can correspond to all of the singularities. To solve this problem, it is tried to use a compounded mesh pattern of two different mesh patterns. One is for one singularity and the other for the other singularity. The displacements for each mesh pattern are superposed. The formulation corresponding to finite element method is given based on the principle of virtual work and the applicability of the method is studied through numerical examples of interface edge problems.
