A well‐conditioned and optimally convergent XFEM for 3D linear elastic fracture
Summary A variation of the extended finite element method for three-dimensional fracture
mechanics is proposed. It utilizes a novel form of enrichment and point-wise and integral
matching of displacements of the standard and enriched elements in order to achieve ...

[PDF] XFEM with global enrichment for 3D cracks
Abstract:[en] We present an extended finite element method (XFEM) based on fixed area
enrichment which 1) suppresses the difficulties associated with ill-conditioning, even for"
large" enrichment radii; 2) requires 50 times fewer enriched degrees of freedom (for a ...

[CITATION] Stable 3D extended finite elements with higher order enrichment for accurate non planar fracture
Abstract We present an extended finite element method (XFEM) for 3D non-planar linear
elastic fracture. The new approach not only provides optimal convergence using geometrical
enrichment but also enables to contain the increase in conditioning number characteristic ...

Abstract:[en] The isogeometric boundary element method (IGABEM) based on NURBS is
adopted to model fracture problem in 3D. The NURBS basis functions are used in both crack
