ABED-MERAIM, Farid; ; ; (American Institute of Physics, 2007)
A microstructural model, based on Peeters' works, is implemented into a large strain self-consistent scheme, leading to the multiscale model which achieves, for each grain, the calculation of slip activity, with help of ... -
Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; BALAN, Tudor (2007)
In this work, an advanced anisotropic elastic-plasticity model is combined with a damage model and a strain localization criterion in the aim to describe accurately the mechanical behavior of sheet metals. Large strain, ...

A large strain elastic-plastic single crystal constitutive law, based on dislocation annihilation and storage, is implemented in a new self-consistent scheme, leading to a multiscale model which achieves, for each grain, ...

Ductility limit prediction using a GTN damage model coupled with localization bifurcation analysis Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Elsevier, 2014)
Because the localization of deformation into narrow planar bands is often precursor to material failure, several approaches have been proposed to predict this phenomenon. In this paper, the Gurson–Tvergaard– Needleman (GTN) ...

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;MERAGHNI, Fodil; ; ; ; (Elsevier, 2015)
With the design of new devices with complex geometry and to take advantage of their large recoverable strains, shape memory alloys components (SMA) are increasingly subjected to multiaxial loadings. The development process ...

Article dans une revue avec comité de lecture; ;MERAGHNI, Fodil (IOP Publishing, 2015)
In the current manuscript, a homogenization framework is proposed for periodic composites with shape memory alloy (SMA) constituents under quasi-static thermomechanical conditions. The methodology is based on the step-by-step ...
