Effective properties of multiphase composites made of elastic materials with hierarchical structure Article dans une revue avec comité de lecture(SAGE Publications, 2015)In this paper, the analytical solution of the multi - step homogenization problem for multi - rank composites with generalized periodicity made of elastic materials is presented. The proposed homogenization scheme may be ...

BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Wiley, 2016)
In an incremental formulation suitable to numerical implementation, the use of rate-independent theory of crystal plasticity essentially leads to four fundamental problems. The first is to determine the set of potentially ... -

A specific in-situ tensile device has been set up in an X-Ray diffractometer. Stress can be measured at low temperature during loading in the baintic steel and in the ferritic phase. A two-scale modeling has been proposed ...

Experimental study of Built-Up Layer formation during machining of High Strength free cutting steel Article dans une revue avec comité de lecture; ; ; ;LESCALIER, Christophe (Elsevier, 2016)
Machinability of high-strength steels can be improved without degrading the mechanical properties using metallurgical solutions to create or retain non-metallic inclusions. Such a metallurgical treatment usually leads, ...

Sheet piles are produced by hot rolling, a cooling step and, if required, by a straightening operation. Numerical simulations indicate that the stress field is almost homogeneous through the thickness, justifying the ...

Conférence invitée; ;PESCI, Raphaël (Jacques Besson, Dominique Moinereau, Dirk Steglich, 2006)
A series of in-situ tensile tests was performed at various low temperatures to characterize the mechanical properties and the fracture processes of the 16MND5 steel: the damage was observed with a SEM and the internal ...
