Hill48 r値
WebHereafter, we call the Hill48 model when using parameters A 1 (r) ∼ A 4 (r) ‘Hill48-r model’, and when using parameters A 1 (σ) ∼ A 4 (σ) ‘Hill48-σ model’. As already well known that, Hill48-r model predicts the planar r-value anisotropy reasonably well for most of sheet metals, but it describes the flow stress directionality too ... WebIn this paper, the limitations of the Hill48 yield model in predicting directional yield stresses and plastic strain ratios (r-values) were investigated. According to a theoretical derivation, …

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.
