THE HUGONIOT EQUATION OF STATE OF 6061-T6 ALUMINUM AT LOW PRESSURES
The Hugoriot equation of state of 6061-T6 aluminum was determined in the pressure region from 0 to 31 kilobars. The one-dimensional shock waves, which were used to compress the medium, were produced by impacting an aluminum target with a flat-nosed projectile. The elastic shock wave velocity was measured as 6.23 plus or minus 0.15 mm/ mu s. Above the Hugoniot elastic limit of 6.3 plus or minus 0.1 kilobars both elastic and plastic shocks were observed. The particle velocity behind the shock front, determined at the plane of impact, was compared to the free surface velocity. Above the elastic limit the free surface velocity was less than twice the initial particle velocity and appeared to be a function of the thickness of the target. (auth)
