The present work critically emphasis on the deformation limit of an elliptical disc. The upper- bound theorem has been used to determine the forging load. A suitable kinematically admissible velocity fields for three dimensional deformations have been chosen for analyzing deformation limit as well as the bulging of disc. During the analysis satisfactory friction factor, yield strength and other process parameter have been assumed and mathematically analyzed. It has been seen that parametric and experimental analysis makes very close agreement. This paper will be worthy for industrial applications in estimating forging load of such shapes.
Key words: Elliptical disc, deformation limit, upper- bound theorem.
