The effect of roll deformation on separating forces in cold strip rolling is studied. The deformed roll shape is determined by a two dimensional finite element routine. The results are then incorporated in an analysis of the mechanics of rolling. The technique consists of assembling individual slabs bounded by planes passing through nodal points on the arc of contact—for each of which an exact solution for the roll pressure is obtained. Comparison to the solution of Orowan’s equations shows that the present technique is reasonably accurate. Comparison to data from a preliminary set of experiments shows that the technique deserves further investigation.
