Naoya Oie et al. / Procedia Structural Integrity 33 (2021) 586–597 Oie, N. / Structural Integrity Procedia 00 (2019) 000–000 model was proposed. The introduction of the factor into the fracture probability improves the consistency with the fracture initiation position. It is necessary to consider the contribution of in the microcrack nucleation process in the brittle fracture elementary process of the local approach. More theoretical and test data-based formulations are needed to clarify the involvement of triaxiality in brittle fracture, as discussed in the last part of the paper.
