S. Su╣, W. Zhang╣, L. Li╣; ╣Aircraft Strength Research Institute, China

Based on the standard Compact Tension Shear (CTS) specimens,The relation between residual strength and loading angle was presented in this paper, and a new fracture criterion was proposed to evaluate its loading ability. The mixed mode crack growth model based on KI and KII was discussed to evaluate the crack growth life of mixed-mode CTS specimens.
