Fig. 2. Plane stress fracture locus of Al6061-T6 alloy. On the other hand, neither criteria provide reliable estimations in the case of Al6061-T6 alloy ( ߗ ൌ ͵ͲͲ MPa, ൌͲǤʹͶ ). Fracture loci of Al6061-T6 alloy are displayed in Figure 2 with the first experiment (Test #1) utilized in the calibration as this experiment is the closest case to a pure shear stress state. The fracture locus (determined by
