This paper discusses the problem of stresses of two joined materials, [I] and [II]. Material [I] is a large plate with an elliptic hole and [II] is an elliptic patch plate. There are two different conditions. One is the difference in the mechanical properties, the other is the difference in the initial elliptic boundary dimensions. Before joining, some amounts of dislocation exist on the elliptic boundaries between [I] and [II]. For continuous connection of both boundaries, we analyzed the necessary boundary tractions, q_x and q_y, theoretically using Goursat's stress functions and Dundurs' parameters. As a result, we obtained generally applicable formulae for expressing q_x and q_y and reported the fundamental numerical calculations in this paper.
