Auto-body panel springback analysis using Yoshida-Uemori model

摘要

The forming process simulation and springback prediction of an automobile body panel is implemented by using JSTAMP/LS-DYNA. Yoshida-Uemori model is selected to characterize the anisotropic material behavior of sheet metal during forming. Simulation predictions on spingback are compared with experiment measurements along with numerical results from other material models to demonstrate the effectiveness and accuracy of the Yoshida-Uemori model.
