Abstract
Split Hopkinson pressure bar (SHPB) setup was used to investigate dynamic constitutive behavior of aerospace Aluminum alloys both experimentally and numerically. The study was conducted in the strain rate regime of 500/s -10000/s. Both regular solid and modified hollow transmission bars were employed in realizing this strain rate regime. Four different Aluminum alloys namely 7075-T4, 2024-T3, 6061-T6 and 5182-O were considered for investigation. Copper-110 alloy pulse shaper was used to obtain better force equilibrium conditions at the barspecimen interfaces. Plastic kinematic model was used to model rate dependent behavior of Aluminum alloys using commercially available LS-DYNA software. It was identified from the final results that experimentally determined dynamic constitutive behavior matches very well with that of numerical in the strain rate regime of 2000/s- 5000/s.
