Abstract: In Part 1 of this paper, simple models of nonuniformities in pressbrake bending in the punch-sheet contact region were presented. An extreme manifestation of these nonuniformities is the appearance ...

Abstract: A simple model of pressbrake bending in the punch-sheet contact region is presented. The pressure and shear stress at the punch-sheet interface cause the stress distribution in the sheet to ...

Abstract: Developed length refers to the length of the unstretched fiber measured over both bent and straight sections of a bent sheet. Bend allowance is a term coined by Sachs as a measure of the ...

Abstract: A semi-analytical method to predict springback in sheet metal forming processes has been developed for the case of plane strain. In the proposed hybrid method, for each deformation increment, ...
