| Abstract: | In this paper,the combined flow model of 3rd order polynomial streamlined velocity field and elemental upper bound thchnique were used in analysis for combined extrusion of round cup-polygonal section rod workpieces. The effects of rod sections on combined extrusion line of demarcation and extresion load were analysed. The theoretical solusion was verified by experiment. |
