ABED-MERAIM, Farid; ; ; (Elsevier, 2009)
In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical ... -
Communication avec acte;ABED-MERAIM, Farid; BALAN, Tudor (2013)
Many criteria have been developed during last decades to predict diffuse or localized necking and shear banding. The lack of confrontation of these models with each other on relevant applications makes their choice difficult ...

Experimentally valided approach for the simulation of the forging process using mechanical vibration Article dans une revue avec comité de lecture; ;GIRAUD-AUDINE, Christophe (Springer Verlag, 2009)
In this study, an experimental setup of a forging process has been designed which allows to apply vibrations to the lower die of amplitude ranging from 0 to 80 ?m at frequencies varying from 1 to 130Hz thanks to the use ...

Article dans une revue avec comité de lecture;ABED-MERAIM, Farid; CHALAL, Hocine; BALAN, Tudor (Springer Verlag, 2012)
This paper proposes an extension of the SHB8PS solid–shell finite element to large strain anisotropic elasto-plasticity, with application to several non-linear benchmark tests including sheet metal forming simulations. ...

Article dans une revue avec comité de lecture;CHALAL, Hocine; BALAN, Tudor (Elsevier, 2012)
The springback behavior of four advanced high-strength sheet steels (Dual-Phase, TRIP, ferrite-bainite) with thicknesses ranging from 1.2 to 4 mm was investigated by means of the bending-under-tension (BUT) test. The ...

Article dans une revue avec comité de lecture(Elsevier, 2011)The response of the tool–chip interface is characterized in the orthogonal cutting process by numerical and analytical means and compared to experimental results. We study the link between local parameters (chip temperature, ...

Article dans une revue avec comité de lecture; ; ; ; ;PESCI, Raphaël (Elsevier, 2012)
This paper presents and analyzes the behaviour of TRIP 1000 steel sheets subjected to low velocity perforation by conical projectiles. The relevance of this material resides in the potential transformation of retained ...
