Abstract:
The ideal flow theory is used to determine an optimal die profile for drawing and extrusion
of sheets under plane strain conditions. The solution is based on the theory of characteristics.
In contrast to available solutions based on the ideal flow theory, it is assumed
that a portion of the die is prescribed. The solution reduces 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.
Keywords:ideal flow, method of characteristics, drawing, optimal die profile.
