In recent years, the dissimilar materials and the composite materials are used for various fields. In the combination with different material constants, the stresses near the intersection of the free-surface and the interface become infinity in the context of theory of elasticity, and the stress singularity might be caused. In general, when the material constants are greatly different, singularity is caused. This singularity becomes serious problem in the numerical analysis. Then, it aims to solve the problem in this research. Materials with different physical properties are combined, and five kinds of dissimilar materials are analyzed by the boundary element method. Moreover, the number of elements in the interface is changed, and the analytical accuracy is examined.
