The dynamic shock responses of eight types of rocks and grouts were determined from one-dimensional plate impact experiments to support the Defense Nuclear Agency (DNA) HYDROPLUS program. Hugoniot data and loading and release paths were measured using in-situ stress gauges and VISAR interferometry. Four rocks, (HUNTERS TROPHY tuff, UTTR limestone, Pennsylvania slate and permafrost phyllite), a high-density silicate grout (BEXGC-1 grout), natural and simulated jointed phyllite and ice were characterized. HUNTERS TROPHY tuff and BEXGC-1 grout were tested in a fully water saturated condition, the other geological materials were tested in their as-received water content condition. Hugoniot data, release adiabats, and propagated wave shapes are presented for the rocks, grout and ice. The permafrost phyllite was characterized in preserved frozen, refrozen and ambient as-received condition. Propagated wave profiles and measured stress wave attenuation rates are given for a naturally jointed phyllite and for phyllite with Danby marble artificial inclusions.
