Dimensional Analysis of Superplastic Processes with the Buckingham Π Theorem
Metals, 2020 This work applies the Buckingham Π theorem from dimensional analysis on superplastic processes in order to obtain laws of behaviour in a simple way. For this reason, a mathematical background is developed.

A method for estimating superplastic material parameters via free–inflation tests
Journal of Materials Research and Technology, 2021 In this work, a new methodology for evaluating the constitutive parameters of superplastic materials is presented. The proposed methodology provides the characterization of the material by means of a variable called apparent viscosity.

A New Approach for Determining the Optimum Pressure–Time Diagram in Superplastic Forming Process [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2013 Superplastic materials show huge amount of deformation in low strain rates and temperature above half of melting point. In superplastic forming, estimating the pressure–time diagram and thickness distribution has significant importance.
