“…The best way of improving fatigue life of SPF'ed parts is to get a thickness distribution as uniform as possible. With this goal, this optimization technique employs non-uniform starting thickness blanks to get uniformly thick final parts [31][32][33][34][35]. In an analogous way, thickness control rings can be added on the initial blank to increase the starting thickness of the sheet in the most critical areas of the sheet [36].…”

Numerical simulation took root in the last few decades in the superplastic forming field as one of the most dominant tools for process analysis and optimization. The big role of the simulation can be found in many areas concerning the study and the implementation of the forming process. The purpose of this paper is to outline some of the main applications of the numerical simulation in superplastic forming that can be found in the material characterization phase, in the simulation of forming tests and in the optimization of the process. A brief overview of results that can be found in literature is given with special regard to Finite Element numerical simulation of metal sheet Superplastic Forming.

“…It is well established that during superplastic deformation, some materials develop cavities which grow and coalesce, leading to cavitation damage [7][8][9][10]. Such damage in turn gives rise to premature failure of the material, thereby, limiting the use of superplastically formed components.…”
