Journal ArticleDOI
A method for dynamic crack and shear band propagation with phantom nodes
TL;DR: In this article, a new method for modeling arbitrary dynamic crack and shear band propagation is presented, where cracks are treated by adding phantom nodes and superposing elements on the original mesh.
Journal ArticleDOI
A meshfree thin shell method for non‐linear dynamic fracture
TL;DR: In this article, a mesh-free method for thin shells with finite strains and arbitrary evolving cracks is described, and the C 1 displacement continuity requirement is met by the approximation, so no special treatments for fulfilling the Kirchhoff condition are necessary.
Journal ArticleDOI
Analysis of three‐dimensional crack initiation and propagation using the extended finite element method
TL;DR: In this paper, a quasi-static analysis of three-dimensional crack propagation in brittle and quasi-brittle solids is presented, where the extended finite element method (XFEM) is combined with linear tetrahedral elements.
Journal ArticleDOI

TL;DR: An extended isogeometric element formulation (XIGA) for analysis of through-the-thickness cracks in thin shell structures is developed in this article, where the discretization is based on Non-Uniform Rational B-Splines (NURBS).
Journal ArticleDOI
Damage and fracture algorithm using the screened Poisson equation and local remeshing
TL;DR: In this paper, a crack propagation algorithm which is independent of particular constitutive laws and specific element technology is proposed, which consists of a localization limiter in the form of the screened Poisson equation with local mesh refinement.
