有限元多晶体模型模拟铝板多点成形过程

Simulation of multi-point forming of aluminium sheet by finite element polycrystal model

采用有限元多晶体模型对板材多点成形过程进行了数值模拟研究 .利用开发的FEPM软件系统 ,预测出典型曲面铝板多点模成形结果 ,给出无弹性垫和使用弹性垫两种变形条件下的等效应力场、等效应变场和平均应力场等 。

Presents numerical simulation of multi point forming of sheet using a finite element polycrystal model. The results of multi point forming of aluminium sheet without or with elastic cushion is predicted by FEPM software developed. Calculated results are compared with experimental results.
