Drawing with heating of box-shaped parts made of anisotropic material

To calculate the force parameters of drawing with heating in the manufacture of box-shaped parts from highstrength materials, relations are obtained using the equation of state of a viscoplastic material. The force mode of drawing is calculated using the upper-boundary extremal theorem of plasticity for a discontinuous field of displacement velocities.
