Fatigue crack growth analysis of welded bridge details
Fracture and Structural Integrity, 2022 The paper investigates the fatigue crack growth in typical bridge weldments by means of numerical analysis. The extended finite element (XFEM) method is coupled with the low-cycle fatigue (LCF) approach in ABAQUS, and parametric analyses are carried out ...

Research on Fatigue Crack Propagation of 304 Austenitic Stainless Steel Based on XFEM and CZM
Metals, 2020 The fatigue crack propagation of 304 austenitic stainless steel was studied both by experiments and numerical simulations. Two methods were applied to simulate the crack propagation: the extended finite element method (XFEM) and the cohesive zone model ...

smooth nodal stress in the XFEM for crack propagation simulations [PDF]
, 2013 In this paper, we present a method to achive smooth nodal stresses in the XFEM without post-processing. This method was developed by borrowing ideas from ``twice interpolating approximations'' (TFEM) [1]. The salient feature of the method is to introduce
