A mixed mode fatigue crack model with the coupled X-FEM/LATIN method. Application to rolling contact fatigue (RCF)

摘要

A new numerical model for fatigue crack analysis is presented in this paper. This model based on linear elastic fracture mechanics for an homogeneous material, uses the extended finite element method (X-FEM). The loading conditions are simulated by normal and tangential contact loads moving steadily over the surface. 2D simulations are presented. The X-FEM stress intensity factors are compared with numerical ones obtained with a fatigue crack model.
