✦ Synopsis

A kinked semi-infinite,crack in an anisotropic mateeal is analyzd. The stress intensity factors of the kinked crack tip are expressed in terms of those associated with the main crack prior to kinking. The asymptotic stress tield around the crack tip is derived for the degenerate case in which the two complex parameters of the anisotropic material are equal. The general results for small kink angles are found to be. in agreament with tho$e derived directly by a perturbation analysis.
