Validation d’une nouvelle version de l’élément solide/coque “SHB8PS” sur des cas tests non linéaires Communication avec acte
ABED-MERAIM, Farid; (2007)
L’intérêt de disposer d’éléments finis volumiques capables de modéliser des structures minces est motivé par de nombreux problèmes industriels. Ainsi, ces dernières années, plusieurs travaux ont été réalisés dans ce domaine. ... -
Communication avec acteBALAN, Tudor; ABED-MERAIM, Farid (Hanrimwon Publishing/ Korean Society for Technology of Plasticity, 2008)
In this work, the finite element method is used to simulate a typical FLD test over tools of different radii. Parameters like the mesh density, element type, numerical determination of the onset of strain localization, ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; BALAN, Tudor (Elsevier, 2008)
Sheet metal forming processes generally involve large deformations together with complex loading sequences. In order to improve numerical simulation predictions of sheet parts forming, physically-based constitutive models ...

Article dans une revue avec comité de lectureCHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 2015)
The localization of deformation into planar bands is often considered as the ultimate stage of strain prior to ductile fracture. In this study, ductility limits of metallic materials are predicted using the Gurson–Tverga ...
