The Hugoniot solid equation of state curve is the curve of pressure and compressibility for a sample material. Compressibility, n, is the ratio of the densities of the shocked material to that of the shock-free material. The shock wave creating the pressure is produced by forcing an aluminum sabot down the barrel of a light gas gun to impact on a pressure transducer. The light gas gun has the desirable ability to reproduce sabot velocities and to produce planar impacts. The theory behind the experiments is in two parts. One part relates the pressure produced on impact to compressibility, and the other relates the pressure incident on the transducer to its electrical output.
