N2 - A detailed analysis of mixed mode I-II crack initiation angles under different loading conditions is presented using different criteria. In addition, the maximum tangential stress criterion (MTS), which was proposed originally for brittle materials, is modified such that it can be used for ductile materials. A variable radius for the plastic core region based on von Mises elastic plastic boundary is introduced and incorporated in the formulation of the MTS-criterion. The limited available experimental data exhibits large scatter, and does not support a certain criterion for different loading conditions. This presents the need for a close examination of the limitations and capabilities of each criterion, which is the main purpose of this study.
