Extended finite element method for cohesive crack growth [PDF]
Engineering Fracture Mechanics, 2002 The extended finite element method allows one to model displacement discontinuities which do not conform to interelement surfaces. This method is applied to modeling growth of arbitrary cohesive cracks. The growth of the cohesive zone is governed by requiring the stress intensity factors at the tip of the cohesive zone to vanish.

Linear smoothed extended finite element method [PDF]
International Journal for Numerical Methods in Engineering, 2017 SummaryThe extended finite element method was introduced in 1999 to treat problems involving discontinuities with no or minimal remeshing through appropriate enrichment functions. This enables elements to be split by a discontinuity, strong or weak, and hence requires the integration of discontinuous functions or functions with discontinuous ...

Modeling crack discontinuities without element‐partitioning in the extended finite element method [PDF]
International Journal for Numerical Methods in Engineering, 2016 SummaryIn this paper, we model crack discontinuities in two‐dimensional linear elastic continua using the extended finite element method without the need to partition an enriched element into a collection of triangles or quadrilaterals. For crack modeling in the extended finite element, the standard finite element approximation is enriched with a ...

Multiscale extended finite element method for deformable fractured porous media [PDF]
Journal of Computational Physics, 2021 Deformable fractured porous media appear in many geoscience applications. While the extended finite element (XFEM) has been successfully developed within the computational mechanics community for accurate modeling of the deformation, its application in natural geoscientific applications is not straightforward.

Modeling curved interfaces without element‐partitioning in the extended finite element method
International Journal for Numerical Methods in Engineering, 2019 SummaryIn this paper, we model holes and material interfaces (weak discontinuities) in two‐dimensional linear elastic continua using the extended finite element method on higher‐order (spectral) finite element meshes. Arbitrary parametric curves such as rational Bézier curves and cubic Hermite curves are adopted in conjunction with the level set method

MethodsX, 2023 We consider a mixed finite element method for a linear multivariate spline using the Laplacian penalty. Our discretisation is based on biorthogonal systems leading to a very simple and efficient finite element scheme.
