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