“…For instance, Kai uses XFEM to create a repaired welding model of welded joints of P91 steel plates with particular cracks [3]. Chen et al build a numerical model by XFEM and experimental investigation of crack growth in T-joints to better understand the mechanisms of crack growth in welded joints [4]. Wang et al also used XFEM for numerical simulation of the fatigue crack growth and suggested developing simple solutions for practical prediction of k M factors [5].…”

This study has used the strain energy density (SED) approach to evaluate the stress intensity factor (SIF) of cracked cruciform welded joints in Hardox 450 steel. A microstructural analysis was made of Hardox 450 steel which is composed of refined and tempered low carbon martensite. The obtained results of simulation will be compared with those provided by J-integral methode for different enriched zones and contours based on the extended finite element method (XFEM) coupled with the level set technique (LST). Crack initiation and propagation under cyclic loading have been adopted for the modeling of cruciform welded joints.
