Several tasks essential to the process design for superplastic forming are treated in conjunction with a computer simulation methodology. In this context, the optimisation of the history of the forming pressure is considered, and the consequences of variations of the material properties. Furthermore, a numerical procedure is presented for the determination of the initial thickness profile of sheets, required for the production of a prescribed distribution of thickness in the formed component. The theory is illustrated by an example.
