Rolling Strips Varying Thickness with Elimination of Widening

“…The plasticity condition for two dimensional deformation is [1] k 2 , for forward slip zone and if the arc of contact is replaced by two chords [2,3], from eq. ( 5) we obtain for backward slip zone ( )…”

“…Widening calculation is based on minimum strength [1]. In rolling, the form of deformation zone from the top is trapezoid with height equal to the length of deformation zone and a width which is equal to average width before and after rolling [2,3].…”
