However, up to now, the theoreticalanalysis for the superplastic constrained bulging has only a few research reports.

The constrained superplastic bulging process is investigated by a large rigid-plastic finite element method.

On the basis of the rigid visco-plastic FEM technique,the numerical simulation of the cavity-damage evoluation process during superplastic bulging process was carried out using the model of cavity-damage evolution deduced from continuous damage mechanics.

In order to shorten forming time and to achieve uniform thickness of parts in superplastic bulging of void-sensitive materials, it is well known that maximum effective strain rate should be kept within a very small range.

Therefore, there will be more practical significance on its practical application to the expansion of the scope of a more complex shape of magnesium alloy parts, whether or not it has superplasticity study under certain conditions using superplastic bulging forming.
