Méthodes XFEM et CutFEM d'ordre 2

, 2023
Ce travail présente les méthodes CutFEM et XFEM, des variantes de la méthode des éléments finis permettant la résolution des problèmes avec interface de discontinuité sans ajuster le maillage à l'interface. D'abord, une formulation discrète, utilisant la méthode de Nitsche, est introduite pour imposer faiblement les conditions d'interface d'un problème

High gradient XFEM for fracture mechanics

, 2012
In this study, a new enrichment scheme in the eXtended Finite Element Method (XFEM) is investigated. The aim is to provide a framework in which a high gradient field can be approximated on fixed meshes. In contrast to the classical approach of mesh refinement in the vicinity of a high gradient, an enrichment procedure with high gradient enrichment ...

Modeling particulate complex flows using XFEM

, 2011
Particulate flows arise in a wide class of research areas and industrial processes, for example, fluidized suspensions, materials separation, rate of mixing enhancement, filled polymers, etc. In many of the applications, the fluid phase displays complex non-Newtonian flow behavior.
