Abstract：

In this paper, the copper busbar CONFORM extending-forming process is simulated by DEFORM software using three dimensional rigid-viscidity plasticity finite element method (FEM) to indicate metal forming mechanism.The metal flow patterns and distributions of stress-effective, strain-effective, temperature and velocity fields are described in detail.Also, the relationship between physical fields of metal forming and real deformation is analyzed in order to provide the theoretical principle for die design and making reasonable metal forming process.
