Communication avec acte;
ABED-MERAIM, Farid; (2013)
Ce travail concerne le développement d’une nouvelle famille d’éléments finis (EF) de type coques volumiques quadratiques. Deux éléments seront présentés, un hexaèdre à vingt nœuds et un prisme à quinze nœuds, qui sont ... -
Article dans une revue avec comité de lecture; ; ;BERVEILLER, Sophie (Centre Mersenne, 2012)
This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts ...

Article dans une revue avec comité de lecture; ;PESCI, Raphaël (Elsevier, 2011)
In this work, the martensitic transformation occurring in AISI 304 steel sheets subjected to tension at room temperature has been experimentally studied. Tensile tests performed on AISI 304 specimens are split into two ...

Many tensile tests have been realized on the 16MnNiMo5 bainitic pressure vessel steel at low temperatures [-196°C, -60°C]. The damaging processes (ductile/fragile) are observed with a scanning electron microscope (SEM), ...

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 lectureABED-MERAIM, Farid; BALAN, Tudor; (Springer Verlag, 2014)
The prediction of forming limit diagrams (FLDs) is of significant interest to the sheet metal forming industry. Although a large variety of plastic instability criteria have been developed during the previous decades, there ...
