| Abstract: | The thickness distribution has important influence on the structure performance of components with thin wall. The technique to predict the thickness distribution of thin components formed by superplastic bulging is studied in this paper. The process of superplastic forming can be simulated numerically by finite element method and the thickness distribution of components can be automatically predicted. The thickness variation of components, which include hemisphere and rectangle pan formed by free and restrained bulging especially, are analyzed and calculated. The predicting results and experiment data accord well together. |
