UPPER BOUND THEORETICAL SOLUTION TO PLANE STRAIN DRAWING THROUGH DIES WITH A CIRCULAR CONTOUR

    Graphical Abstract
    • Abstract
  • A continuous velocity field referred to rectangular coordinatesis proposed to plane strain drawing through dies with a circular profile. A parametric integration and integral as a function of the upper limit are applied. And an upper bound analytical solution was obtained.
