Phase-Field Regularized Cohesive Zone Numerical Modeling
摘要
In order to describe fracture behavior in structural materials, this research investigates the effectiveness of the phase-field technique, concentrating on the Phase Field Cohesive Zone model (PF-CZM). Using COMSOL Multiphysics, a bar under uniaxial traction has been simulated with the linear model AT1, the non-linear model AT2, and the cohesive model. Numerical results show that PF-CZM can provide a more realistic representation of material behavior, where deformations can propagate progressively before eventual failure.
