Results of an experimental study on the dynamic properties of 6061-T6 aluminum are presented. Areas studied included stress-strain-strain rate and reverse loading behavior, elastic constants, equation of state, compressive and release wave characteristics, and spall fracture. The shock wave equation of state EOS calculated from the elastic constants and comparisons made with the shock wave EOS. Compressive wave tests showed a well-defined elastic precursor with a steady-state value of approximately 5 kbar. The yield level from shock wave profile measurements was approximately the same as that determined from uniaxial stress and EOS tests. The impact velocity required for spall fracture was found to increase with decreasing pulse width, and to decrease with increasing temperature.
