摘要

Analytical and numerical methods are presented which allow to predict the kinking angle of a semi-infinite crack in the vicinity of a thermally and elastically mismatched circular inclusion. In order to obtain this angle the maximum circumferential stress criterion will be evaluated. To this end the mixed-mode stress intensity factors (SIFs) at the crack tip must be known as functions of thermal and elastic mismatch as well as of geometry. They follow from solution of a system of singular integral equations for the dislocation densities which are used to model the crack. For arbitrary elastic mismatch and for an arbitrarily oriented crack only a numerical solution can be obtained. However, if the crack tip and the inclusion are sufficiently separated and if the elastic mismatch is not too large the integral equations can be solved analytically. Consequently, in this case closed-form solutions for the SIFs and for the kinking angle can be obtained.
