Abstract：

On the basis of rigid\|plastic material model and 3\|D film elements, the process of hemispheric bulging is analysed. Flow characteristic of the deformation area and influence of material parameters on deformation are researched. To verify the reliability of FEM results, the stress distribution of deformation is measured with mesh method, and the analysis results are compared with the experimental results.
