| Abstract: | In the paper rigidity-viscoplasticity finite element formulas are derived on the basis of variational principle for the rigid-viscoplastic material and the viscoplastic flow stress equations are established through experiments. The program RVP-11 which suit to hot extrusion of axisymmetric steel pipe is designed. An influence of the extrusion speed, temperature, extrusion ratio, friction condition on the extrusion press is analysed too. |
