Description To make a comparison with existing experimental results in the field today, and to determine experimental values other form-factor, were realized, testing of specimens produced from two different alloys based on Al (SUPRAL 100, FORMALL) of various thicknesses at various deformation temperatures. The experimental study was followed by a parameterized finite element analysis of the process, using Ansys® this is for considering the next step of our study, to compare experimental results with theoretical analysis, depending on two input parameters: and discuss the results. The parameterized analysis has the main objective to discover and emphasize the role of each input parameter on the evolution of the process, mainly on the output parameters, chosen by the operator. It is known that processing by superplastic forming is a process whose duration is superior to the similar plastic deformation processes
