The prediction of plastic instability in sheet metals during forming processes represents nowadays an ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion, is proposed ... -
Article dans une revue avec comité de lecture;PESCI, Raphaël (Elsevier, 2017)
The microstructural response of a coarse grained AISI 304 stainless steel submitted to biaxial tensile loading was investigated using SEM and X-ray diffraction. The specimen geometry was designed to allow for biaxial stress ...

In modern sheet metal forming processes, such as hydroforming and single point incremental forming, sheet metals are often subjected to out-of-plane compressive stresses in addition to traditional in-plane stresses. However, ...

Conférence invitée; ; ;MERAGHNI, Fodil (2017)
Dans ce travail, un modèle micromécanique établi sur le principe de l’homogénéisation périodique est utilisé pour décrire le comportement macroscopique des composites à matrice thermoplastique sous chargements cycliques ...
