High-order extended finite element method for cracked domains [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2005
The aim of the paper is to study the capabilities of the Extended Finite Element Method (XFEM) to achieve accurate computations in non smooth situations such as crack problems. Although the XFEM method ensures a weaker error than classical finite element methods, the rate of convergence is not improved when the mesh parameter h is going to zero because ...

Modelling crack growth by level sets in the extended finite element method

open access: yes, 2001
An algorithm which couples the level set method (LSM) with the extended finite element method (X‐FEM) to model crack growth is described. The level set method is used to represent the crack location, including the location of crack tips.

Interaction Analysis of Non-aligned Cracks Using Extended Finite Element Method

open access: yesLatin American Journal of Solids and Structures
Multiple flaws are frequently occurred in actual components, such as pressure vessels and power plants. These flaws will in some circumstances lead to more severe effects than single flaw alone.
