Abstract: A three-dimensional kinematically admissible continuous velocity field bas been established for drawing rectangular workplace through a parabolic die. Then, applying the in tegral as a function of the upper limit and the curved surface integral, an upper bound analytical-solution of the dra wing stress has been obtained.

Key words: curved surface integral, three-dimensional deformation, parabolic die
