A dynamic high-pressure triaxial test device was developed for use in formulating soil and rock constitutive relations used in blast-induced ground shock calculations. The device is capable of imposing controlled impulsive-type confining pressures up to 15 kipssq in on specimens up to 3 inches in diameter peak pressures can be achieved in as little time as 3 msec, and all pressure can be removed in 20 msec. These dynamic confining pressures can be time- synchronized with similar dynamic axial load pulses with magnitudes up to 100 kips.
