Abstract
The ideal flow theory is used to determine the optimal die profile for the drawing and extrusion of sheets under the conditions of a plane strain. The solution is based on the theory of characteristics. In contrast to the available solutions based on the ideal flow theory, it is assumed that a portion of the die is prescribed. The solution is reduced to evaluating ordinary integrals. As an example, a die profile is found assuming that a portion of this profile is given and is a circular arc.
