Advances in Plastic Anisotropy and Forming Limits in Sheet Metal Forming

Abstract

In the last decades, numerical simulation has gradually extended its applicability in the field of sheet metal forming. Constitutive modeling and formability are two domains closely related to the development of numerical simulation tools. This paper is focused, on the one hand, on the presentation of new phenomenological yield criteria developed in the last decade, which are able to describe the anisotropic response of sheet metals, and, on the other hand, on new models and experiments to predict/determine the forming limit curves.
