Abstract：

In this paper, the upper bound method is used to build the extrusion flow model of Aluminum Shape in Flat Container ,i.e. the model of indentical extrusion ratio.The flow equation is established with 3rd order polynome. The kinematically admissible velocity field , the strain rate field and the deformation power are formulated. The optimum numerical solution of the relative stress is obtained. The effects of extrusion ratio , the section of container and the product on the extrusion force are analyzed. The calculated curves of the relative stress for various A/B ratio of the container are obtained. They are useful.The theoretical results are compared with known experimental data and are found to be in good agreement.
