Improvement in Prediction Accuracy of Springback for Stamping CAE considering Tool Deformation

Effect of Constitutive Equations on Prediction Accuracy for Springback in Cold Stamping of TRIP1180

The objective of this study is to evaluate the effect of constitutive equations on the prediction accuracy for springback in cold stamping with various deformation modes. In this study, two types of yield functions—Hill’48 and Yld2000-2d—were considered to describe yield behavior. Isotropic and kinematic hardening models based on the Yoshida–Uemori model were also adopted to describe hardening ...
