Abstract

Basic boundary integral equations are presented for an elastic body with cracks, where the existance of boundaries other than the crack surfaces are taken into account. The unknown functions of the integral equations are displacement-discontinuities on the crack surfaces and displacements or surface tractions on the boundaries other than the crack surfaces. Four crack problems are analyzed; i. e., problems for an annular crack, a fiat elliptical crack, a curved circular crack and a fiat square crack near a traction free surface, and it is shown that the method presented here are flexible for various kinds of crack problems.
