Condition
- Condition
- EN AW-6014 automotive aluminium sheet in T4 temper used for multi-stress-state forming tests
- Temper
- T4
- Heat treatment
- T4 as supplied; detailed solution-treatment and natural-ageing schedule not stated
- Product form
- sheet
- Thickness / diameter range
- 2.0 mm
- Test direction
- rolling direction for tensile tests and measured Young's modulus; aligned rolling directions in layer-compression stacks

- Notes
- Exact EN AW-6014-T4 2 mm sheet and experiment geometry are retained. The modulus is measured in RD; Poisson's ratio is explicitly assumed; plasticity parameters are fitted to an extrapolated experimental flow curve and verified across twelve experiments. Failure parameters and manufacturer-datasheet minima are excluded.
