Abstract: Main stress method is widely used in engineering calculations. In this paper, the formula for calculating the extrusion-deformation-force of circular cone tube are derived from main stress method . The result can be used as a reference for designing mould and selecting process equipment.

Key words: Conical shells, Principal stress, Extrusion, Deformation
