A constitutive model is applied to predict the flow stress of an fcc material up to 30% straining after rolling to reductions of 19%, 39%, and 50%. The model makes use of a single crystal hardening law which appreciates the directional anisotropy produced by planar dislocation boundaries, Bauschinger effects, and dissolution of substructure by new slip activity invoked by changes in strain path. Anisotropy between axial testing in the rolling (RD) versus the transverse direction (TD) and a tensioncompression stress- differential in RD are predicted. These and other characteristics of the flow curves are linked to changes in slip activity when deformation transitions from rolling to axial testing.
