Abstract
The dependence of the flow stress on the orientation of the stress axis in the plane of textured zinc sheet has been investigated, both experimentally and theoretically. The theoretical investigation consisted of simulating the deformation process by using a generalized Taylor model (based on the minimum-work condition) and the Sachs model (based on the Schmidt shear-stress law). The deformation modes considered were slip and mechanical twinning. Only with the Taylor model was the orientation distribution consistent with the experimentally determined pole figures. The work done and the flow stress for a given plastic strain were therefore calculated for this orientation distribution using the Taylor model. The calculated and measured quantities exhibited the same directional dependence. This anisotropy can be attributed to the different activations for basal and pyramidal slip systems. MST/80Keywords
