dc.description.abstractSpringback is one of the most common problems in the sheet metal forming operation. In the literature there have been numerous studies about springback and its compensation for many material groups. Illustrations of these phenomena for the sheet metals have still been going on by using the numerical and the experimental tools. Nowadays, the finite element method is the most powerful tool for determining of the springback characterization of the sheet metals. The selection of the material models which are used in the finite element software for the simulation of the forming operation and springback are very important in terms of accurate predictions. In the present study, formability and springback characterization of the TRIP800 steel are investigated by finite element analysis method using different material models, i.e. Hill-48, Barlat-89, and YLD2000. Additionally, the capability of the Hill-48 and Barlat-89 on predicting the variation of the yield stress and anisotropy values with respect to the angle from rolling direction is investigated for different methods like Lankford parameters and ErrMin approaches. Results reveal that the variation of the yield stress and anisotropy values that obtained from experiments at different directions like 0 degrees 45 degrees, 90 degrees can be predict better with ErrMin method. Among the studied anisotropic yield criteria, YLD2000-2d has the best fit to the yield stress and anisotropy values. According the finite element simulation of V-die bending processes YLD2000-2d has the best prediction capability of the springback. (C) 2012 Elsevier Ltd. All rights reserved.
