Modelling of the rolling process—I: Inhomogeneous deformation model

The rolling of material results in the inhomogeneous plastic deformation of the material in the arc of contact between the rolls. To assess the influence of this inhomogeneous deformation, the parameter, ω, developed by Orowan has been incorporated into a theoretical model of the rolling process. The results are compared with recent results published by Alexander in which the assumption of homogeneous deformation or ‘plane sections remaining plane’ was considered.
