A microstructural model, based on Peeters' works, is implemented into a large strain self-consistent scheme, leading to the multiscale model which achieves, for each grain, the calculation of slip activity, with help of ... -

The influence of twinning on the strain hardening rate and fracture mechanism in AZ31B magnesium alloy was studied in this work by in situ microstructural analysis during tensile testing in a chamber of scanning electron ...

In this investigation, thermo-viscoplastic behaviour of austenitic steel AISI 304 has been characterised in tension under wide ranges of strain rate at room temperature. This metal possesses an elevated strain hardening ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; ; ; (Elsevier, 2011)
In this paper, the effects of microstructure and deformation mechanisms on the ductility of multiphase steels are investigated. To this end, a formability criterion based on loss of ellipticity of the boundary value problem ...

Ce travail consiste à étudier par simulation le phénomène du retour élastique dans le procédé d’emboutissage des tôles métalliques. Un modèle phénoménologique d’élasto-plasticité, incluant deux modèles d’écrouissage combiné, ...

Communication avec acteABED-MERAIM, Farid; (Krzysztof Dems [et al.], 2007)
In this study, the formulation of the SHB8PS solid-shell element is reviewed in order to eliminate some persistent membrane and shear locking phenomena. The resulting physically stabilized and locking-free finite element ...

Ductility limit prediction using a GTN damage model coupled with localization bifurcation analysis Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 2014)
Because the localization of deformation into narrow planar bands is often precursor to material failure, several approaches have been proposed to predict this phenomenon. In this paper, the Gurson–Tvergaard– Needleman (GTN) ...
