The dynamic behavior of three aluminum alloys 6061-T6, 2014-T6 and 2024-T3, is described from experimental tests in three areas 1 Effect of prestraining on the subsequent yield surface in biaxial stress, 2 Effect of heating rate or time-at-temperature on the yield and flow stress behavior in uniaxial stress, and 3 Shock wave response where elastic constants, hugoniot equation of state, wave profiles, and spallation thresholds were determined. Experimental techniques are fully described with emphasis on data interpretation within the limitations of the experiments. Results are presented with analysis and discussion related to current theoretical formulations.
