Conférence invitée
ABED-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; ;MERAGHNI, Fodil (Elsevier BV, 2021)
A new hybrid homogenization approach is proposed for simulating the homogenized and local response of unidirectional fuzzy fiber nanocomposites undergoing inelastic deformations. Fuzzy fiber composites are hierarchical ...

Article dans une revue avec comité de lecture; ; ; ; ; ;PESCI, Raphaël (Elsevier, 2021)
A novel single shear specimen (SSS) together with a correction coefficient method is used to study the deformation behavior of a 304 stainless steel under shear loadings. Shear stress-shear strain relations over a wide ...

Communication sans acteJEBAHI, Mohamed; ; ABED-MERAIM, Farid (2020)
Thanks to their capabilities in capturing size effects, strain gradient plasticity theories have received a strong scientific interest in the last two decades. However, despite the great scientific effort on these theories, ...

Communication sans acteCHALAL, Hocine; ABED-MERAIM, Farid (2018)
In this work, nonlinear dynamic analysis of thin structures is investigated using quadratic solidshell (SHB-EXP) elements. The proposed SHB-EXP elements are based on a fully three-dimensional formulation using an in-plane ...

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 ...
