Units
Condition
- Condition
- fully annealed EN AW-5049-O thin-wall seamless tube
- Temper
- O (fully annealed)
- Heat treatment
- 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.
