Tension-Compression Tests for Springback Prediction of AHS Steel Using the Yoshida-Uemori ModelYoshida-Uemori modelTension-compression testAHS steel sheetSpringbackIn sheet metal forming process of automotive parts, the springback effect is crucial, in particular, for advanced high strength (AHS) steels....
The Yoshida-Uemori model was used as a representative kinematic hardening model in this study. Tensile tests and tensile-compressive cyclic loading tests were performed on 980 DP steel to obtain the parameter values for the Yoshida-Uemori model. Finite element analysis was performed using the ...
The modified Yoshida-Uemori two surface hardening model is applied to investigate the effect of work hardening stagnation. This novel model is examined on the Numisheet 2011 benchmark 4. The effects of the blank holder force and work hardening stagnation are studied on the sheet springback ...
In this paper, we describe the stress-strain relationship for remanufacturing, in particular the cyclic deformation of parts, by using the particle swarm optimization (PSO) method to acquire the Yoshida-Uemori (Y-U) hardening model parameters. To achieve this, tension-compression experimental data ...
