CHALAL, Hocine; ABED-MERAIM, Farid (2017)
Dans ce travail, les limites de ductilité associées à l’apparition d’une localisation des déformations sont prédites en utilisant le modèle d’endommagement de Gurson couplé à la théorie de bifurcation. Une étude paramétrique ... -
Communication avec acte;CHALAL, Hocine; ABED-MERAIM, Farid (AIP Publishing, 2019)
For biaxial stretching strain paths, which are typically encountered in sheet metal forming, the stress triaxiality ranges from 0.33 to 0.67. At this low level of triaxiality, voids change their shape from spherical to ...

Communication avec acte; ;BALAN, Tudor; ABED-MERAIM, Farid (2017)
The aim of this work is to develop a dislocation density based model for IF and DP steels that incorporates details of the microstructure evolution at the grain-size scale. The model takes into account (i) the contribution ...

Article dans une revue avec comité de lecture;FROMENTIN, Guillaume; VIPREY, Fabien; ; (Society of Manufacturing Engineers, 2021)
Inconel 718 is widely used in aircraft industry due to its properties. Nevertheless, its mechanical and chemical properties make it hard-to-cut. As a consequence, additive manufacturing is developed in order to get near ...

Communication avec acte;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Elsevier, 2016)
It is well known that both damage and plastic anisotropy strongly affect the ductility limit of thin metal sheets. Due to the manufacturing processes, initial defects, such as inclusions and voids, are commonly present in ...

This work is focused on the effect of natural defect on the fatigue resistance of a laser powder bed fusion additively manufactured Ti-6Al-4V titanium. To reveal the fatigue strength variability and its sensitivity to the ...

Article dans une revue avec comité de lecture; ; ;MERAGHNI, Fodil (Elsevier BV, 2022)
In this paper, an original probabilistic micromechanics damage framework involving multi-deformation mechanisms, based on the modified Mori-Tanaka and Transformation Field Analysis (MT-TFA) techniques, is developed to ...
