Journal ArticleDOI
On the construction of blending elements for local partition of unity enriched finite elements
TL;DR: It is shown that an appropriate construction of the elements in the blending area, the region where the enriched elements blend to unenriched elements, is often crucial for good performance of local partition of unity enrichments.
Journal ArticleDOI
The extended finite element method (XFEM) for solidification problems
TL;DR: In this article, an enriched finite element method for the multi-dimensional Stefan problems is presented, where the standard finite element basis is enriched with a discontinuity in the derivative of the temperature normal to the interface.
Journal ArticleDOI
An Extended Finite Element Method for Two-Phase Fluids
Jack Chessa,Ted Belytschko +1 more
TL;DR: The finite element approximation can capture the discontinuities at the interface without requiring the mesh to conform to the interface, eliminating the need for remeshing.
Journal ArticleDOI
An extended finite element method with higher-order elements for curved cracks
TL;DR: In this paper, a finite element method for linear elastic fracture mechanics using enriched quadratic interpolations is presented, which is enriched with the asymptotic near tip displacement solutions and the Heaviside function so that the finite element approximation is capable of resolving the singular stress field at the crack tip as well as the jump in the displacement field across the crack face.
Journal ArticleDOI
An Eulerian–Lagrangian method for fluid–structure interaction based on level sets
TL;DR: In this paper, a method for fluid-structure interaction with the interface and free surfaces defined by level sets is described, where the fluid is treated by an Eulerian mesh whereas the solid or structure by a Lagrangian mesh.
