Abstract: In-plane tension-compression experiments of TRIP800 steel were conducted with a self-developed device. Based on the experiments, the Yoshida-Uemori (Y-U) hardening model was built and verified, which was then used to analyze the springback of the U-shaped part. The results show that more springback is achieved on the Y-U model than that based on isotropic model.

Key words: metal material, TRIP high strength steel, in-plane tension-compression tests, Yoshida-Uemori model, springback
