| Abstract: | In this paper,the rigid viscoplastic element formulas are derived according toa new constitutive relationship,and are applied to the numerical simulation of three-dimensional plastic compression of metals. The influences of the material hardening expo-nent(n) and rate sensitivity(m) on deformation of three-dimensional plastic compression of metals are analysed. |
