Abstract
To predict the yield surfaces of textured sheet metals, two methods were conducted. The first method (crystallographic yield surface) is based on the Taylor-Bishop-Hill (TBH) polycrystal model, using the orientation distribution function (ODF) of the material as an input. The second method (phenomenological yield surface) makes use of phenomenological yield functions based on mechanical test data. Anisotropic properties for six texture components typical of aluminum alloy sheets were examined and the results based on crystal plasticity were compared with the results based on phenomenological yield functions. The experimental anisotropy measurements obtained for an AA6xxx sheet were also compared to crystallographic and phenomenological predictions.
