A Fracture Criterion for Prediction of Fracture Initiation of Metal Materials at Various Stress States for Nuclear Waste Storage

Table 3

The position of maximal triaxiality at crack tip and the maximal principal stress and the maximal shear stress at the position where the maximal stress triaxiality is located in the loading conditions from mode I to mode II.
