A model is developed to determine the geometric and deformation characteristics of copper strips during alternating elastoplastic bending with a decreasing radius of curvature. This model is experimentally shown to satisfactorily correspond to the real conditions of deformation of commercial-purity copper strips on a roll leveling machine. The maximum effect of this processing is found to consist in a significant (by three–five times) increase in the yield strength of copper strips in only one pass. The developed model can be used to find the boundary of alternating deformation at which the entire cross section of the strip passes into the elastic deformation zone.
