Off-line path programming for three-dimensional robotic friction stir welding based on Bézier curves Article dans une revue avec comité de lecture(Emerald, 2018)Robotic friction stir welding (RFSW) is an innovative process which enables solid-state welding of aluminum parts using robots. A major drawback of this process is that the robot joints undergo elastic deformation during ...

BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (2016)
The aim of this paper is to develop a new efficient integration scheme, able to integrate the constitutive equations for rate-independent theory of crystal plasticity at finite strain. This algorithm proposes an efficient ... -
Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ; ABED-MERAIM, Farid ; ; (Elsevier, 2020)
Elasto-plastic multiscale approaches are known to be suitable to model the mechanical behavior of metallic materials during forming processes. These approaches are classically adopted to explicitly link relevant microstructural ...

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 ...
