A cohesive XFEM model for simulating fatigue crack growth under various load conditions
article
This study presents calibration and validation of a cohesive extended finite element model forfatigue crack propagation in ductile materials. The approach relies on a separation betweenplasticity around the crack tip and fatigue crack growth at the crack tip such that the influenceof plasticity on fatigue driving forces is predicted. This implies that characterization of crackgrowth requires effective Paris parameters. It is shown that the calibrated model can capturefatigue crack growth behaviour in ductile materials for in-phase and out-of-phase biaxial fatigueloading as well as in-phase biaxial loading with an overload
