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 ...

The development of a relevant constitutive model adapted to sheet metal forming simulations requires an accurate description of the most important sources of anisotropy, i.e. the slip processes, the intragranular substructure ...

The main objective of this study is to simulate texture and deformation during the temper-rolling process. To this end, a rate-independent crystal plasticity model, based on the self-consistent scale-transition scheme, is ...

Article dans une revue avec comité de lecture(Elsevier, 2015)Magnetic Shape Memory Alloys (MSMAs) have been the subject of much research in recent years as potential high-actuation-energy multifunctional materials. In this work we analyze coupled magneto-mechanical stability analysis ...

Article dans une revue avec comité de lecture(Elsevier, 2015)In this paper we present an internal variable-based homogenization of a composite made of wavy elastic-perfectly plastic layers. In the context of a strain-driven process, the macrostress and the effective yield surface ...

Article dans une revue avec comité de lecture; ;MERAGHNI, Fodil; ; (Springer, 2015)
In the present study, a new transformation criterion that includes the effect of tension–compression asymmetry and texture-induced anisotropy is proposed and combined with a thermodynamical model to describe the thermomechanical ...
