Kinked cracks in an anisotropic material

[[abstract]]A kinked semi-infinite crack in an anisotropic material is analyzed. 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 field 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 agreement with those derived directly by a perturbation analysis.[[fileno]]2020232010014[[department]]動機
