| Abstract: | In the paper, the incremental function of strain and displacement of themetallic deformation region can be defined by the functional equilibrium method of extremum principle when workpiece is extruded through the cone mould. On the base ofthe incremental fanction, a calculation formula of extruding pressure is obtained bymeans of the principle of energy balance. This formula is available to the engineeringpractice. |
