In this work, nonlinear analysis of an embedded cracked plate is performed by XFEM in presence of multiple discontinuities under plane stress condition. Von-Mises yield criterion is used to model the elasto-plastic behavior of the plate assuming isotropic strain hardening. The stress-strain response of the plate is modeled using Ramberg-Osgood material model. XFEM is used as a numerical tool to simulate the plate containing a major centre crack, holes and inclusions. A domain based J-integral approach is used to evaluate the stress intensity factors. The generalized Paris law is used to estimate the fatigue life of the plate under mode-I cyclic loading condition. The effect of inclusions and holes on the fatigue life of the component for linear and nonlinear material behavior is discussed in detail.
