ABED-MERAIM, Farid; (2009)
Une nouvelle formulation de l'élément solide–coque SHB6 est décrite. Il s'agit d'un élément isoparamétrique prismatique à 6 noeuds, interpolation linéaire et intégration réduite dans le plan moyen. Les déplacements sont ... -

polymers. In the case of magneto-sensitive polymers, micron-size ferromagnetic particles are mixed with a liquid polymeric matrix in the uncured stage. The polymer curing process is a complex process that transforms a fluid ...

High strain rate visco-damageable behavior of Advanced Sheet Molding Compound (A-SMC) under tension Article dans une revue avec comité de lectureSHIRINBAYAN, Mohammadali; FITOUSSI, Joseph; MERAGHNI, Fodil; ; ; TCHARKHTCHI, Abbas (Elsevier, 2015)
Advanced Sheet Molding Compound (A-SMC) is a serious composite material candidate for structural automotive parts. It has a thermoset matrix and consists of high weight content of glass fibers (50% in mass) compared to ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; BALAN, Tudor (Springer Verlag, 2008)
This work aims to study the strain localization in different sheet metal forming processesby the finite element method using advanced behaviour models. In order to improve the prediction of the formability limit of sheets ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; (MDPI, 2013)
An advanced elastic-plastic self-consistent polycrystalline model, accounting for intragranular microstructure development and evolution, is coupled with a bifurcation-based localization criterion and applied to the numerical ...

Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid; BALAN, Tudor (E. Oñate, D.R.J. Owen, D. Peric and B. Suárez, 2011)
The strain localization phenomenon that may occur during sheet metal forming represents a major cause of defective parts produced in the industry. Several instability criteria have been developed in the literature to predict ...
