説明
Fracture at joint-tips in a closing mode (KI < 0), which is opposite from the opening mode (KI > 0), is discussed upon an analysis of the pure mode I crack propagation from tips of kinked joints, taking an overall slide on the joint surface and a possible closure of the joint into consideration. The stress intensity factors {KIB, KIIB} at tips of kinks are accurately analyzed by the Stress Compensation-Displacement Discontinuity Method (SC-DDM), and they are successfully applied to the pure mode I crack propagation analysis, which is conditioned only by KIIB = 0. The fracture initiation in the closing mode is evaluated by minimizing the size of kink and open-crack in the model, and it is clarified that the fracture locus in the closing mode is well described by the maximum circumferential stress criterion which is widely used to evaluate the fracture initiation in the mixed mode of the opening mode and in-plane sliding mode.
