Thickness and strain rate at the sheet dome apex in superplastic bulge forming tests

Thickness and strain rate at the sheet dome apex in superplastic bulge forming tests 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Material Forming Springer Journals

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.
