Points massiques, hyperbole et hyperboloïde à une nappe

Jean-Paul Becar, Lionel Garnier, Lucie Druoton

Les courbes de Bézier rationnelles quadratiques jouent un rôle fondamental pour la modélisation d'arcs de coniques propre. Cependant, lorsque les deux points extrémaux de l'arc ne sont pas sur la même branche d'une hyperbole, l'utilisation des courbes de Bézier classiques est...

Separation of the elastic waves’ system in pre-stretched bar devices

Grégory Haugou, Nicolas Leconte, Hervé Morvan

The loading mode generated by Kolsky bars apparatus is limited due to physical reasons to a duration time of around 0.4ms. This is not suited in the characterization of high ductility metallic alloys up to fracture at moderate strain rates, since the duration time is too short. The pre-stretched...

Thermal conductivity modeling of Alumina/Al functionally graded composites

Christine Pelegris, Nabil Ferguen, Willy Leclerc, Yannick Lorgouilloux, Stéphane Hocquet, Olivier Rigo, Mohamed Guessasma, Emmanuel Bellenger, Christian Courtois, Véronique Lardot, Anne Leriche

This paper describes a new manufacturing process for producing functionally graded ceramic‐metal composites with anisotropic properties for thermal management in automotive engine blocks. These composites are elaborated by producing a porosity gradient within an alumina matrix, subsequently...

Region of exponential stability of switched linear systems on time scales

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper deals with the stability analysis of a class of linear time-invariant switched systems on non-uniform time domains. The considered class consists of a set of linear continuous-time and linear discrete-time subsystems. Some sufficient and necessary conditions are derived to guarantee the...

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...
