CHALAL, Hocine; ABED-MERAIM, Farid (ACEX, 2016)
In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ... -
Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 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 ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (EDP Sciences, 2016)
A family of prismatic and hexahedral solid‒shell (SHB) elements with their linear and quadratic versions is presented in this paper to model thin 3D structures. Based on reduced integration and special treatments to eliminate ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (AIP, 2016)
A family of linear and quadratic assumed-strain based solid‒shell elements (SHB) is presented in this paper to simulate 3D thin structural problems including both quasi-static and dynamic analyses. The SHB solid‒shell ...

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 ...

Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier BV, 2021)
In this paper, four plastic instability criteria, which are based on the bifurcation theory, are coupled with the GTN damage model for the prediction of diffuse and localized necking. General bifurcation (GB) criterion and ...
