Dynamic recrystallization observed at the tool/chip interface in machining

Yannick Senecaut, Michel Watremez, Julien Brocail, Laurence Fouilland-Paille, Laurent Dubar

In numerical approaches for high speed machining, the rheological behavior of machined materials is usually described by a Johnson Cook law. However, studies have shown that dynamic recrystallization phenomena appear during machining in the tool/chip interface. The Johnson Cook constitutive law…

A viscoelastic-viscoplastic model for short-fibre reinforced polymers with complex fibre orientations

Mariem Nciri, Delphine Notta-Cuvier, Franck Lauro, Fahmi Chaari, Bassem Zouari, Yamen Maalej

This paper presents an innovative approach for the modelling of viscous behaviour of short-fibre reinforced composites (SFRC) with complex distributions of fibre orientations and for a wide range of strain rates. As an alternative to more complex homogenisation methods, the model is based on an…

Friction Analysis in Bulk Metal Forming

Laurent Dubar, André Dubois, Mirentxu Dubar

A methodology to characterize friction according to the severe conditions of contact encountered in metal forming is presented. The main peculiarity of the proposed method is to use specimens and contactor made of industrial tool and workpiece surface in laboratory bench tests in order to ensure…
