Abstract
The antiplane strain problem for bonded dissimilar half planes of general anisotropic material containing an inclined crack terminating at the bimaterial interface is considered. The surfaces of the crack can be subjected to traction-traction, traction-displacement or displacement-displacement boundary conditions. The dependence of the order of the stress singularity on the inclined angle and material constants is studied. If the effective crack angle and the effective material constant are introduced for the anisotropic case, then the characteristic equation which determines the order of the stress singularity has the same functional form as the isotropic case. Explicit solutions for the order of stress singularity are obtained for some special cases. It is found that the order of the stress singularity is always real for all the cases studied in this paper. This is a quite different character from the in-plane case in which the complex type of stress singularity might exist. The angular distribution of stresses near the crack tip and the exact full field stress solutions are also investigated. © 1990.
