Abstract: In this work, stable crack growth behavior of SA508 carbon steel has been evaluated through experimental and numerical investigations. The effect of various types of flaws has been observed on the load carrying capacity of the structures. A homogenized multigrid XFEM approach has been proposed to simulate the stable crack growth in ductile material using finite strain plasticity. The geometric nonlinearity has been modeled by updated Lagrangian approach whereas the material nonlinearity has been modeled by von-Mises yield criterion using isotropic strain hardening. The accuracy and effectiveness of the proposed approach has been verified by solving several stable crack growth problems. © 2016 Elsevier Ltd
