BENAARBIA, Adil (Elsevier, 2020)
This paper presents experimental and numerical investigations to study spatial-temporal distributions of strain heterogeneities within a FV566 turbine rotor steel subjected to high temperature conditions. Strain field were ... -
Article dans une revue avec comité de lecture;BENAARBIA, Adil; ; MERAGHNI, Fodil (Elsevier, 2020)
This paper presents an experimental approach aimed at analyzing and validating a two-scale nonlinear Finite Element (FE 2 ) simulation of a 3D composite structure. The studied composite material consists of polyamide ...

Formability prediction of substrate-supported metal layers using a non-associated plastic flow rule Article dans une revue avec comité de lectureBEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Elsevier, 2021)
When manufacturing flexible devices, it is quite common that localized necking appears due to the low ductility of the metal sheets used. To delay the inception of such localized necking, several industrial companies have ...
