TL;DR: A number of macroscopic and microscopic models which have been proposed for reproducing the forward and reverse flow behavior are discussed in this paper, and some of the strengths and weaknesses of the models have been discussed in the light of experimental data available from quasi-static forward and backward loading tests on a variety of materials.

TL;DR: In this article, a method of evaluating the strains over the deformed surface of a stamping is described, which is intended as the basis of an interactive computer design aid capable of dealing with typical stampings, including deep parts and complex shapes.

TL;DR: In sheet metal forming operations, the principal failure modes are localized necking or wrinkling, and the strain in the sheet at the time when localization occurs is usually referred to as the Limit Strain, i.e. the principal surface strains ∈11 and ∈22.

TL;DR: In this paper, the authors dealt with the pure bending of bonded laminated metals under plane strain conditions, where each laminate is classified by its initial yield strength, work-hardening characteristics and its percentage thickness in relation to the whole sheet.

TL;DR: In this paper, the authors used a finite element analysis to predict the optimal blank shapes for asymmetrical cup drawing operations using plane stress characteristics, which correspond with the predicted profiles correspond with experimentally determined optimum blank shapes when deep drawing square cups.
