Controlling thickness variation during pneumothermal forming in the superplastic regime

Abstract

Results are presented from the modeling of different methods of controlling thickness fluctuations in superplastic pneumothermal forming. Recommendations are given on the use of each method and a part made of titanium alloy VT-20 is used as an example to show the thickness distribution over the part for each method. © 2013 Springer Science+Business Media New York.
