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 ... -

Conférence invitée; ; ;MERAGHNI, Fodil (Scheven Malte von; Keip Marc-André; Karajan Nils, 2017)
Shape memory alloys (SMAs) are exploited in several innovative applications such as biocompatible actuators experiencing up to large number of cyclic loads. However, the description of the SMA cyclic response is still ...

Conférence invitée;PRAUD, Francis; ; ; ; MERAGHNI, Fodil (2017)
Dans ce papier, une technique de modélisation multi-échelle (EF2) basée sur le principe d’homogénéisation périodique a été développée pour décrire le comportement des structures composites 3D avec un comportement ...
