Mixed-mode fatigue crack growth using cohesive zone modeling
Engineering Fracture Mechanics, 2020 Abstract In order to capture nonlinear crack tip behavior and account for mixed-mode fatigue crack growth, a cohesive zone based fatigue crack growth model is proposed in conjunction with the Park-Paulino-Roesler (PPR) traction-separation relationship.
