Thickness and strain rate at the sheet dome apex in superplastic bulge forming tests
Source abstract
Abstract
This paper discusses evaluating and controlling sheet dome apex thickness during constant pressure superplastic bulging tests. An accurate thickness value, associated with the H-t curve (normalized polar height-forming time curve), helps determine the equivalent strain rate at the sheet dome apex. The numerical results were confirmed in experimental bulging tests carried out on a tin-lead alloy sheet which is superplastic at room temperature.
