Abstract:This paper estimates the internal stresses of two joined materials which have different initial size displacements. Material [I] is an infinite plate having an elliptical hole. Material [II] is an elliptical inclusion. They have a discrepancy between [I] and [II] of the elliptic boundary. Furthermore, their materials have different mechanical properties. For continuous connection of both boundaries, we provide the boundary tractions and analyze them. The related report published by previous authors did not consider an initial size displacement of both materials boundaries and had several errors at derived formulas. In this paper we show correct results. Several numerical results are given by graphical representation.
