Article dans une revue avec comité de lecture(Elsevier, 2021)The effective and localized electro-magneto-elastic behavior of periodic unidirectional composites is investigated in this work. Instead of adopting the classical micromechanics models or variational principle-based ...

Ductile failure is the main mechanism that limits the formability of thin metal sheets during forming processes. In the current contribution, ductile failure is assumed to be solely induced by the occurrence of localized ... -
Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Wiley (Holm Altenbach), 2021)
In this paper, we study some qualitative and numerical properties of new equations including the coupled effects of thermal elastic-plastic theory with microtemperatures. We establish the necessary and sufficient conditions ...

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 ...

We present in this investigation an advanced phenomenological approach combining the computational efficiency of classical phenomenological plasticity models and the accuracy and high resolution of multiscale crystal ...
