Abstract: Plastic instabilities, such as the Portevin-Le Chatelier (PLC) effect, reduce material ductility and induce surface roughness during sheet metal forming. The formation and propagation of PLC bands have been extensively studied by using the uniaxial… read more here.

Abstract: The strain path dependence of forming limit curve (FLC) restricts its practical application for formability evaluation as the real strain path of material point in true industrial forming processes is often non-linear. In this work,… read more here.
