| Abstract: | In the present paper,the superplastic bulging with a die under constant pressure is simulated by using visco-plastic finite element method. The flowing trace of material points and sectional shape of the bulging specimen are given and the influences of the geometric parameters n the contacting sequence and contacting site of the elements are analysed. |
