MERAGHNI, Fodil; ; (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad/ Wiley, 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 ... -
Conférence invitée; ;MERAGHNI, Fodil (Haddar, M., Romdhane, L., Louati, J., Ben Amara, A. / Springer, 2013)
In the present work, a new polycyclic fatigue damage model is formulated and applied for short glass fibre reinforced thermoplastics. The model is able to capture experimental trends observed for the considered composites. ...

Kossel microdiffraction in a scanning electron microscope enables determination of local elastic strains. With Kossel patterns recorded by a CCD camera and some automation of the strain determination process, this technique ...

Conférence invitéeABED-MERAIM, Farid; ; (E. Oñate, D.R.J. Owen, D. Peric and M. Chiumenti, 2015)
In the present work, diffuse necking is investigated for stretched metal sheets using two different approaches, namely bifurcation theory and maximum force principle. The contribution includes a critical analysis and a ...

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. ...

A physically based elasto-visco-plastic constitutive model is presented and compared to experimental results for a DD14 mild steel. The model requires significantly fewer material parameters compared to other visco-plasticity ...

La nature biphasée de l’acier bainitique 16MND5 (ferrite/cémentite) fait de la Diffraction des Rayons X (DRX) l’outil privilégié pour déterminer les états de contrainte dans la phase ferritique (méthode des sin2 ψ). Couplés ...
