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 ... -

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 lectureABED-MERAIM, Farid; (Wiley, 2009)
In this paper, the earlier formulation of the SHB8PS finite element is revised in order to eliminate some persistent membrane and shear locking phenomena. This new formulation consists of a solid-shell element based on a ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; BALAN, Tudor (Elsevier, 2009)
Sheet metal forming processes generally involve large deformations together with complex loading sequences. In order to improve numerical simulation predictions of sheet part forming, physically-based constitutive models ...

Article dans une revue avec comité de lectureABED-MERAIM, Farid; (Hermès / Paris : Lavoisier, 2007)
In this work, the formulation of the SHB8PS finite element is reviewed in order to eliminate some persistent membrane and shear locking phenomena. This is a solid-shell element based on a purely three-dimensional formulation. ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; ; ; (Elsevier, 2009)
Sheet metal forming processes are commonly associated with strain-path changes in the material. Macroscopic softening/hardening transient effects can appear due to the plastic anisotropy induced by these deformation stages. ...
