Web14 hours ago · On the one hand, the initial attempt by incorporating cohesive zone model (CZM) into the phase-field approach [74] is to address the cohesive fracture, where the dissipative mechanism is different from brittle fracture. The phase-field variable, as an auxiliary field, enables the incorporation of cohesive traction during crack opening.
