摘要：

The effect of mode I and equivalent mixed mode and mode II overload on subsequent mode I crack propagation was studied on compact tension shear specimens of D16AT Al alloy. It was observed that the retardation period is considerably affected by the contribution of the mode II component. Fractographic analysis of the fracture surfaces was carried out by observing the fracture surfaces under a Scanning Electron Microscope.
