What is Nonlinear XFEM Analysis of Crack Growth about?
The article presents an analysis of fatigue crack growth in a center crack plate using the Extended Finite Element Method (XFEM), focusing on the impact of defects and plasticity on fatigue life. A Ramberg-Osgood material model is employed to assess the stress-strain behavior, and the J-integral is utilized to evaluate stress intensity factors for different fracture modes. Results from linear and elasto-plastic analyses are compared to highlight the effects of plasticity-induced crack closure on fatigue lif
