FITOUSSI, Joseph; MERAGHNI, Fodil; SAINTIER, Nicolas (Elsevier, 2014)
This paper aims at studying fatigue damage behavior of injection molded 30 wt% short glass fiber reinforced polyamide-66 composite (PA66/GF30). The evolution of dynamic modulus, hysteresis area, cyclic creep and temperature ... -

The technology of nitrogen jets impacting surfaces at low temperature has recently been introduced for surface cleaning/stripping. Under the impact of the jet, the material surface undergoes a thermomechanical shock inducing ...

Thixoforming of steels poses challenges due to the high temperatures involved and the lack of understanding of thermomechanical behavior. The volume fractions of the liquid and solid phases in the semi-solid state are the ...

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;CHALAL, Hocine; ABED-MERAIM, Farid ; 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. ...

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 ...
