4. Discussion According to Fig. 4 and 5, the kinematics of strip deformation is quite different in comparison with the analytical solution (Fig. 1). That means that elastic region significantly disturbs boundary conditions, which were used for analytical solution using rigid-plastic scheme. Moreover, analyzing stress distribution performed in work [8] it is
