XFEM for Deformation Theory of Plasticity
PAMM, 2015AbstractIn this work, an approach is presented to improve global accuracy properties for physically non‐linear problems in the frame of elastoplasticity. The work is motivated by the fact that convergence characteristics of a finite element solution are dominated by the regularity of the exact solution. For a material undergoing inelastic deformations,

XFEM for Fracture Analysis in 2D Anisotropic Elasticity
Advances in Applied Mathematics and Mechanics, 2017Summary: In this paper, a method is proposed for extracting fracture parameters in anisotropic thermoelasticity cracking via interaction integral method within the framework of extended finite element method (XFEM). The proposed method is applied to linear thermoelastic crack problems.

A COMPARISON BETWEEN THE NMM AND THE XFEM IN DISCONTINUITY MODELING
International Journal of Computational Methods, 2012Discontinuities such as voids, cracks, material interfaces, and joints widely exist in nature. Conventional finite element method (FEM) requires the finite element mesh to coincide with the discontinuities, which often complicates the meshing task. When evolution of discontinuities are necessary, remeshing is inevitable, which makes the simulation ...

XFEM-VCCT for Composite Delamination
International Journal of Computational MethodsCohesive Element Method (CEM), the most popular method for composite delamination, suffers from rigorous element size requirements and great computational cost. In this work, the Extended Finite Element Method (XFEM) and Virtual Crack Closure Technology (VCCT) are combined to develop XFEM based on VCCT (XFEM-VCCT) for delamination analysis for the ...

REgularized XFEM for meso-macro scale problems
2010A meso-macro scale approach based on a REgularized eXtended Finite Element Method (REXFEM) is presented. The macro-scale problem contains an additional length scale, called hereafter meso-scale length, which is smaller than the structural scale. The meso-scale length can represent, for instance, the thickness of the adhesive layer in bonded composites,

A REGULARIZED XFEM FRAMEWORK FOR CONTINUOUS/DISCONTINUOUS DISPLACEMENTS
2009A numerical strategy for modelling both diffuse and localized cracking in elastodamaging continua is proposed. The approach is based on the REgularized eXtended Finite Element Method (REXFEM), which has been presented in [1] [2] for assigned interfaces of elastic and cohesive type.

XFEM simulation of delamination in composite laminates
Composites Part A: Applied Science and Manufacturing, 2016Abstract In this paper, the extended finite element method (XFEM) is extended to simulate delamination problems in composite laminates. A crack-leading model is proposed and implemented in the ABAQUS® to discriminate different delamination morphologies, i.e., the 0°/0° interface in unidirectional laminates and the 0°/90° interface in multidirectional
