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 ...

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 ...
