Extended finite element method for electromagnetic fields [PDF]
2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2015 This paper presents the fundamental principle of the extended finite element method (XFEM) for electromagnetic field analysis. This method provides an accurate approximation for locally non-smooth features within finite elements, such as singularities, discontinuities, and high derivatives.

Smoothed extended finite element method for continua [PDF]
, 2009 The extended finite element method (XFEM) introduced by Belytschko [1] allows discontinuities to be arbitrarily present in the domain, i.e, discontinuities can be independent of the mesh. However this complicates the numerical integration of the stiffness matrix, because it requires subdivision of elements cut by discontinuity, which in 3D may be ...

A Multigrid Method for a Nitsche-based Extended Finite Element Method [PDF]
International Journal of Computing and Visualization in Science and Engineering, 2021 We present a tailored multigrid method for linear problems stemming from a Nitsche-based extended finite element method (XFEM). Our multigrid method is robust with respect to highly varying coefficients and the number of interfaces in a domain.

Use of the XFEM for the design of adhesively-bonded T-joints
Fracture and Structural Integrity, 2019 The use of adhesive bonds greatly increased in industrial applications, as they have multiple advantages compared to other more traditional bonding methods (fastened, welded and riveted joints).

Mixed Integration Scheme for Embedded Discontinuous Interfaces by Extended Finite Element Method
Frontiers in Earth Science, 2022 The extended Finite Element Method (XFEM) is derived from the traditional finite element method for discontinuous problems. It can simulate the behavior of cracks, which significantly improves the ability of finite element methods to simulate ...
