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 ...

A combined space-time extended finite element method [PDF]
International Journal for Numerical Methods in Engineering, 2005 The Newmark method for the numerical integration of second order equations has been extensively used and studied along the past fifty years for structural dynamics and various fields of mechanical engineering. Easy implementation and nice properties of this method and its derivatives for linear problems are appreciated but the main drawback is the ...

Shock and Vibration, 2017 We model the fluid flow within the crack as one-dimensional flow and assume that the flow is laminar; the fluid is incompressible and accounts for the time-dependent rate of crack opening.

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.
