Stronger and weaker singularity of an inclined crack terminating at the orthotropic bimaterial interface

摘要

The attention is focused to the development of techniques for evaluation of stress singularities and generalized stress intensity factors (GSIF) pertaining to the case of an inclined surface crack terminating at the interface between two orthotropic materials. The knowledge of the regular and auxiliary solution allows evaluating the GSIF using the reciprocal theorem (Ψ-integral). A co-operating effect of a stronger and a weaker singular stress field for a crack impinging a bimaterial interface is investigated.
