A new description of cracks in the XFEM [PDF]
PAMM, 2011 AbstractThis work outlines an approach that combines the advantages of explicit and implicit descriptions of the crack geometry in the context of the extended finite element method (XFEM). The XFEM is typically combined with an implicit description of the crack which is realized by the level‐set method.

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 ...

The optimal XFEM approximation for fracture analysis [PDF]
IOP Conference Series: Materials Science and Engineering, 2010 The extended finite element method (XFEM) provides an effective tool for analyzing fracture mechanics problems. A XFEM approximation consists of standard finite elements which are used in the major part of the domain and enriched elements in the enriched sub-domain for capturing special solution properties such as discontinuities and singularities ...

Numerical Fatigue Analysis for Crack Propagation on Ti6Al4V Panel Using XFEM Method
Macromolecular Symposia, EarlyView.ABSTRACT The aim of this work is the validation of a numerical model based on the XFEM method for the prediction of crack propagation in mechanical components subjected to cyclic loads. Through careful bibliographic research, it was decided to take as a case study the analysis of the propagation of a crack passing through a panel in an additive ...
