A cohesive XFEM model for simulating fatigue crack growth under various load conditions

This study presents calibration and validation of a cohesive extended finite element model for fatigue crack propagation in ductile materials. The approach relies on separation between plasticity around the tip growth at such that influence driving forces is predicted. implies characterization requires effective Paris parameters. It shown calibrated can capture behaviour materials in-phase out-of-phase biaxial loading as well with an overload.
