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
Processing route
commercial automotive sheet; wire-eroded tensile specimens and stacked circular blanks
Temperature range
Test temperature is not stated; no temperature extrapolation is allowed.
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.
