WebHill48 yield function is enough to describe anisotropy of CR1180TRIP for the sheet metal forming simulation. To obtain the coefficients of Yoshida-Uemori model, which is one of the most advanced material models for spring-back simulation, the tension/compression test was performed for two pre-strains as shown in Figure 2(b). WebJun 2, 2024 · anisotropic yield criteria, namely Hill48 and Yld2000-2d were implemented in the model. The Hill48 yield model was applied with non-associated flow rule to comprehend the effect of variations in both yield stress and R-values. The numerically estimated FLDs were validated after comparing with FLD evaluated through experiments.
