本文根据简化三维单元,建立了分析立轧非稳态过程的刚—粘塑性有限元列式,提出了产生初始速度场的新方法,成功地分析了铅块立轧非稳态过程,得到的结果与实验吻合较好。
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.
