|Abstract:||This study investigates the initiation of mixed-mode crack extensions in four-point bend and shear specimens fabricated from aluminum alloys. The determination of fracture initiation utilizes a new strain detection method, which provides a uniform criterion for specimens over the complete mixed-mode I-II loading range. The 0.2. mm offset method for mode I specimens and the physical features on the fracture surface of mode II dominant specimens validate this method. The total measured fracture toughness shows a minimum value for the pure mode I case, a maximum for the pure mode II case and an oscillated trend over the mixed-mode I-II loads. © 2012 Elsevier Ltd.|
