WebIn this paper, the Hill1948 model is used as the plastic potential, ˜ p, under the plane stress assumption. because this model can eectively describe the strain anisotropy. Under the plane stress condition considering sheet metal forming, the plastic potential function is given as below [17]: ˜= (2) 1 2 e ∶C ˜e where e − p ˜ = (3 ...

WebDec 7, 2010 · Hill 1948 Yield Criterion. Many of you, I am sure, use Von Mises as a yield criterion to calculate the equivalent stress and strain on your system. I am using Hill 1948 as it provides an anisotropic analysis. However, I am having trouble calibrating Hill48 using the r-values. where r0 is the rolling angle direction and r90 the transverse direction. WebJan 27, 2015 · The fracture criterion was characterized for an AZ31 Mg alloy plate with the 3.0 mm thickness at the elevated temperature of 250 °C in this work. In order to properly characterize the fracture criterion, its mechanical properties were also characterized. As for mechanical properties, simple tension tests were performed to calibrate the Hill1948 yield …
