In this paper, we present of strain singular field at cross point of surface and cuboidal inclusion. The Element Free Galerkin method(EFGM) was used for discussion of strain singular field. Recently, lightening of machine structures are done as a purpose of energy conservation. Stress and strain singularity occurs at vertex on interface in bonded structure when external load is applied to the dissimilar material joints, and it might be induced delamination or crack. Therefore, it is necessary to clarify the characteristic of the singularity near interface. In this study, strain singular field at cross point of surface are computed with dissimilar material joints that consists of resin and Aluminum.
