fully annealed before testing; time, temperature and cooling schedule not stated
Product form
thin-wall seamless round tube
Thickness / diameter range
32.00 mm outside diameter x 1.50 mm nominal wall; 150.00 mm bulge-specimen length
Test direction
multiaxial T-branch tube bulging with axial feeding
Processing route
seamless commercial tube, fully annealed, T-shape hydraulic bulge test
Temperature range
The hydraulic-bulge test temperature is not explicitly stated.
Notes
The inverse and classical analytical parameter pairs are retained as separate method-dependent identifications for the exact fully annealed tube. They are not interchangeable with the tensile fit, an EN minimum or a general material allowable. The paper reports three repeated tube specimens for the selected loading path, but raw data require a request to the corresponding author. The source's one '5409-O' text inconsistency is explicitly documented rather than silently corrected.
