Rigid-Plastic Finite-Element Analysis of Plane Strain Rolling

The plane-strain rolling problem was solved by the rigid-plastic finite-element method based on the infinitesimal theory of plastic deformation. Both nonsteady-state solutions and steady-state solutions were obtained. The velocity field in the deforming material and the external forces along the arc of contact were obtained. From these quantities, roll separating force, roll torque, and roll pressure distributions, as well as stress and strain fields, were calculated. A series of cases with different dimensions and material properties were analyzed and the results were compared with experiments found in the literature.
