| Abstract: | Closed-form solutions are obtained for the stress and die pressure distributions, time and flow rates for drawing and extruding superplastic cylinders through a cone-shaped die with Coulomb friction. Numerical examples are presented graphically and the possible existence of a maximum limit for area reduction in the drawing process is pointed out and discussed. |
