The h-refinement is a technique to achieve the mesh adaptation during a finite element simulation. Some elements are selected because the error is higher than a given threshold: they are split. This operation creates new elements where the size of th

In this paper, a modal analysis for computation of stress intensity factors under dynamic loading conditions at low frequency using eXtended Finite Element Method (X-FEM) is conducted. Modal stress intensity factors for a body with a stationary crack

In this paper, an Extended Finite Element Method (X-FEM) axisymmetric model is developed and employed to compute stress intensity factors for cracked industrial specimens and components. The X-FEM model implementation is first validated by the analyt

This paper presents a 3D non-locking contact approach, within the eXtended Finite Element Method (X-FEM) framework. X-FEM allows one to introduce interface independently of the mesh. The contact problem on the interface leads to an Augmented Lagrangi

International audience; G-theta method with appropriate virtual crack extension (theta field) is proposed for the accurate evaluation of energy release rate along a crack edge which is non-orthogonal to the free surface. This method is implemented in

The extended finite element method (X-FEM) has been developed to minimize requirements on the mesh design in a problem with a displacement discontinuity. This advantage, however, still remains limited to the small deformation hypothesis when consider

Meshing issues in the context of the finite element method (FEM) are often difficult ones to deal with, as in the case of modelling helix-shaped cracks in rotor shafts (Andrier et al. [1]). As a matter of fact, 3D automatic meshing programs often gen
