Dynamic compression and release experiments on Indiana limestone
A series of shock wave experiments designed to assess Hugoniot states, waveforms and release curves for water-saturated and dry Indiana Limestone has been conducted over the pressure range of 1-11 GPa. Strength effects dominate the response of the saturated samples below 4 GPa, with the shock velocity extrapolating to the ambient longitudinal velocity. Rarefaction shocks are observed at 3 and 4.5 GPa. The Hugoniot above 4 GPa is consistent with the formation of CaCO/sub 3/ /center dot/ 6H/sub 2/O (ikaite), which is unstable below 0.5 GPa at room temperature. The dry limestone Hugoniot is slightly stiffer than predicted. Initial releases for both materials are nearly along the Hugoniot both at low and high pressures. 10 refs., 3 figs.
