Computational methods of the superplastic forming duration of a round membrane

Resumo

The methods for calculating the duration of the superplastic forming of a circular membrane are considered. The results of calculations by analytical formulas are compared with the solution of boundary-value problems of the theory of creep and viscoplasticity found in the medium of the ANSYS software complex. The values of material constants were determined by the data of uniaxial tests and testing formings of the VT6 titanium alloy (Ti–6Al–4V).
