TL;DR: In this paper, an original technique based on finite element method was proposed to determine the optimum pressure-time profile in superplastic forming processes, and the proposed technique was tested with reference to the forming of a thin circular plate clamped in a rigid die and formed by a pressure differential.

TL;DR: In this paper, the authors present an algorithm for superplastic forming processes, with finite element interface capability, that can calculate the load curve to be applied during forming, which makes it possible to maintain the maximum strain rate as near as possible to the optimum characteristic value of the material thereby reducing forming time.

TL;DR: In this article, the authors proposed a method to characterize superplastic materials based on the approximate analysis of a super-plastic forming process in a triangular indefinite prismatic-shaped die.

TL;DR: In this paper, the authors introduce the study of the growth of void intentionally premachined on specimen subject to tensile test: in particular the effects of the material parameters on the void growth will be analyzed.
