Abstract:
The rigid-viscoplastic finite element formulations for the analysis of non-stationary deformation in the edge rolling is established on the basis of the simplified 3-D. element. A new method for obtaining inital velocity field is developed in this paper. It has been used successfully to analyse the non-stationary deformation in the edge rolling of lead plates. The calculated results are found to be in good agreement with those obtained from expriements.
