AMOUZOU-ADOUN, Yaovi Armand; JEBAHI, Mohamed; FIVEL, Marc; FOREST, Samuel; LECOMTE, Jean-Sebastien; SCHUMAN, Christophe; ABED-MERAIM, Farid (2023-04-03)
Bien qu’ils présentent des fortes capacités en matière de prédiction des effets de taille, les modèles de plasticité à gradient développés dans la littérature manquent encore de maturité pour être appliqués dans le monde ... -
Article dans une revue avec comité de lectureCHALAL, Hocine; SALAHOUELHADJ, Abdellah; ABED-MERAIM, Farid (Wiley-VCH Verlag, 2012)
In this paper, the performance of the solid-shell finite element SHB8PS is assessed in the context of sheet metal forming simulation using anisotropic elastic-plastic behavior models. This finite element technology has ...

Communication avec acte;LEMOINE, Xavier; HADDAG, Badis; ABED-MERAIM, Farid (Springer, 2005-04)
This contribution concerns the implementation in the FE code Abaqus/Explicit of anisotropic elastoplastic behaviour laws for sheet metal forming. Several hardening laws are considered: isotropic hardening (Swift, Voce), ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (Luso Impress S.A. Publisher, 2015)
A family of prismatic and hexahedral assumed-strain based solid–shell elements (SHB elements), with their linear and quadratic versions, are presented in this work to model thin structures. These SHB elements are based on ...

Communication avec acte;BALAN, Tudor; ABED-MERAIM, Farid (Edizioni Progretto, 2005-10)
The deep drawing is one of the widely used processes in industry to give suited forms to metal sheets. During deformation the sheet and tools undergo high stresses. The sheet must carry on the deformation until the end of ...
