MERAGHNI, Fodil (2016)
In this work, the influence of the direction and the history of thermomechanical loading of NiTi shape memory alloys on the overall material behavior is experimentally investigated. In the first part, cyclic biaxial ... -
Conférence invitéePRAUD, Francis; ; ; MERAGHNI, Fodil (2016)
In this paper, a micromechanics model, based on the periodic homogenization method, is utilized to study thermoplastic woven composites. The proposed approach accounts for the microtructure effects and the local behaviour ...

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 ...

Article dans une revue avec comité de lecture(Elsevier, 2016)In the present article, the homogenization of a composite star-shaped tube with numerous thin, periodic, elastic wavy layers, is presented. The composite exhibits a multiscale periodicity allowing for a multistep asymptotic ...

Article dans une revue avec comité de lecture; ; ; ; ;PESCI, Raphaël (Elsevier, 2016)
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 ...

Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Argentinean Association of Computational Mechanics, Brazilian Association of Computational Mechanics, Mexican Association of Numerical Methods in Engineering and Applied Sciences, 2016)
The aim of this paper is to investigate the impact of the microscopic yield surface (i.e., at the single crystal scale) on the forming limit diagrams (FLDs) of face centred cubic (FCC) materials. To predict these FLDs, ...
