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-...
Recently, the kinematic hardening Yoshida-Uemori model has showed great capability for predicting elastic recovery of material. In this work, the AHS steel grade JSC780Y was investigated, in which tension-compression tests were carried out. From resulted cyclic stress-strain responses, material ...
