Abstract
In this paper with Von Kármán's basic assumptions a kinematically admissible continuous velocity field has been established to drawing through parabolic dies (or called trumpet dies). Then by using the curvilinear and the integral as a function of the upper limit an upper bound analytical solution of the drawing stress is obtained.
