Abstract
The technique of Sheet Stamping by Deformable Forming Tools (SSDFT) has been recognized as a promising alternative to control the springback of sheet blanks. This paper deals with the springback of elastic-plastic circular plates on deformable dies subjected to transverse external forces. Different significant parameters are examined within the framework of the present investigation. For instance, the influence of the friction coefficient between the workpiece and elastomer on the equivalent plastic strain and, therefore, on the springback, for different boundary conditions, are investigated in detail. Moreover, the effects of the thickness of the workpiece on the springback, for both deformable and conventional dies, are discussed.
