| Abstract: | he forging process is a problem concerning large plastic deformation, so that this paper adoptedthe comoving coordinate to follow the tracks of flowing particls, and used the energy method to calculate, stepby step, increment of displacement, effective strain field, etc. Owing to change of the coordinate in companywith the forging blank, the functional of total energy of deformation and the functions and parameters concerned were shown in the form of tensors. The results calculated have been verified by experiments. |
