Abstract: The kinematically admissible velocity and strain rate fields for drawing and extrusion through a hyperbolic die are established in this paper.The curvilinear integral and the integral as a function of the upper limit are used for obtaining friction and deformation powers.An analytical solution of mean plane extrusion and drawing stresses is obtained for hyperbolic dies.

Key words: curvilinear integral, hyperbolie die, extrusion and drawing
