| Abstract: | The kinematically admissible velocity field and strain rate field for extension forging of rounds have been established. Based on the twin-shearing stress yielding criterion. an analytical solution is obtained by upper bound theorem. Compared with that from the traditional slab method. the solution can give higher accuracy. |

| Keywords: | extension forging continuous velocity field twin-shearing stress criterion upper-bound analytical solution. |
