This paper deals with singularity of residual stress produced in edge-bonded rectangles of dissimilar materials using a theory of eigen value and numerical analysis of boundary element method. It was clear that the singularity of residual stress field is the same as that of mechanical field from connecting stress functions of Muskhelishvili with a theory of eigen function. The method of calculating the singularity of rectangles bonded by diffusion bonding was proposed by using similar law and numerical analysis. It was shown that the residual stress distribution of bonded dissimilar materials was more important than the singularity of those for investigating reasonable combination of materials or estimating a joint-strength of dissimilar materials.
