Application of G. Lame’s and J. Gielis’ formulas for description of shells superplastic forming

The paper shows that the contour of a sheet blank at all stages of superplastic forming can be described by application of the universal equations known as a "superformula" and "superellipse". The work provides information on the ranges of values of the coefficients entering thes...
