- Abstract
- The present paper aims at a detailed analysis of sheet metal formability using the physically-based hardening model accounting for the evolution of the anisotropic work-hardening induced by the microstructural evolution at large strains of Teodosiu and Hu (1995) [9]. The onset of localized necking is simulated by an advanced sheet metal forming limit model which connects, through the Marciniak-Kuczinsky analysis, the respective microstructural hardening model with the phenomenological anisotropic yield criterion Yld2000-2d (Barlat et al., 2003) [17]. Linear and complex strain paths are taken into account. The selected material is a DC06 steel sheet. An exhaustive study on the evolution of internal variables of the microstructural hardening model under such loadings is presented. The origin of the increase/decrease of formability under specific strain path changes is discussed. (C) 2011 Elsevier B.V. All rights reserved.
