抄録

The three dimensional stress analysis usually is much complicated ; sometimes, however, it is rather easier in an anisotropic elastic body, the solution of which contains one of an isotropic body as a degenerated case. The present paper concerns a stress analysis in a normal-anisotropic body with a circum-ferential crack, uniformly extended or subjected to a couple of concentrated forces. By use of the stress functions formulated by Higuchi, the boundary conditions are expressed in dual integral equations. The solution is obtained and the stress field near the crack tip, the stress-intensity factors and the crack extension stress criteria are presented.
