International audience; Fatigue lifetime prediction of cracked parts is a difficult problem with the standard finite element method. It is necessary to remesh the crack at each propagation step. This remeshing procedure is complex in 3D and take much

International audience; Numerical crack propagation schemes were augmented in an elegant manner by the X-FEM method applied to fracture mechanics. The use of special tip enrichment functions, as well as a discontinuous function along the sides of the

Contribution à l'étude des méthodes des équations intégrales et à leur mise en œuvre numérique en élastoplasticité

Autor: Burgardt, Bertrand

Publikováno v: Mécanique [physics.med-ph]. Ecole Centrale de Nantes (ECN), 1999. Français

This study deals with Boundary-Domain Element Methods (BDEM) applied to small-strain elastoplasticity. The governing equations are obtained by using the Somigliana displacement identity with initial strains and unlike in Finite Element Methods (FEM),
