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;BEN BETTAIEB, Mohamed; ; ABED-MERAIM, Farid ; ; (Elsevier BV, 2021)
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 ...

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 ...

Article dans une revue avec comité de lecture(Elsevier, 2021)A two-phase near- beta titanium alloy (Ti–10V–2Fe–3Al, or Ti-1023) in its as-forged state is employed to illustrate the feasibility of a Bayesian framework to identify single-crystal elastic constants (SEC). High Energy ...

Communication avec acte;JEBAHI, Mohamed; ABED-MERAIM, Farid (2019)
Strain gradient crystal plasticity (SGCP) represents a very promising way to account for size effects in miniaturized components, thanks to the intrinsic length scale(s) embedded. Most of the existing SGCP models are based ...
