| Abstract: | A new method :simplified slip-line approach to the analysis for the axisymmetric forming of metals is discussed in this paper, and the simplified slip-line solution of extrusion pressure to the axisymmetric backward extrusion of the cup-shape part has been obtained. The result show that simplified slip-line solution is less than the upper bound solution, more approachable to the ture load. It is a convenient and practical method for determing the force required for deformation in the axisymmetry forming. |
