Web6 okt. 2024 · Here, we construct the equivalent crack-tip cohesive zone laws representing a phase-field fracture model, to elucidate the effects of G c and l c on the fracture resistance and crack growth mechanics under mode I K-field loading. Our results show that the cohesive zone law scales with increasing G c while maintaining the same functional form. WebHofacker, M., & Miehe, C. (2012).
