Communication avec acte;
CHALAL, Hocine; ABED-MERAIM, Farid (ESAFORM, 2020)
During the last decades, a family of assumed-strain solid-shell finite elements has been developed with enriched benefits of solid and shell finite elements together with special treatments to avoid locking phenomena. These ... -
An anisotropic model with linear perturbation technique to predict HCP sheet metal ductility limit Communication avec acte;BEN BETTAIEB, Mohamed; ; ; ; ABED-MERAIM, Farid (2021)
In this paper, hexagonal closed packed (HCP) sheet metal ductility for a viscoplastic material is analyzed by using a linear perturbation technique. It can be used for the analysis of localized necking. This technique is ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (2016)
In this work, an elastic–plastic model with Hill’48 anisotropic yield surface is coupled with the continuum damage mechanics theory and combined with the bifurcation analysis, in order to predict strain localization in ...

Communication avec acteCHALAL, Hocine; ABED-MERAIM, Farid (ACMA, 2016)
In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented ...

Conférence invitéeABED-MERAIM, Farid (2018)
In the literature dealing with plastic instabilities in general, many instability criteria have been developed, and some of them have been extensively applied to sheet metals to investigate their formability limits. ...

Article dans une revue avec comité de lecture; ; ;PESCI, Raphaël (Elsevier, 2021)
A thermomechanical analysis on a 320 × 256, 30 μm pitch, middle wave infrared detector operating at 100 K is conducted. The stress induced in the HgCdTe single crystal layer needs to be minimized to avoid electro-optical ...

Dans ce travail, les limites de ductilité associées à l’apparition d’une localisation des déformations sont prédites en utilisant le modèle d’endommagement de Gurson couplé à la théorie de bifurcation. Une étude paramétrique ...
