MEASUREMENTS OF SHOCK AND DETONATION PRESSURES
UTAH UNIV SALT LAKE CITY INST OF METALS AND EXPLOSIVES RESEARCH
Pagination or Media Count:
An aquarium technique for the measurement of shock and detonation pressures is described which is capable of measuring accurately pressures over a range extending from roughly one to several hundred kilobars. An experimental determination of the equation of state for water, upon which use of the aquarium technique relies, is presented and compared with results obtained by other investigators. Similar data are presented for lucite. Measurements of pressures at the detonation front for a variety of explosives including both ideal and nonideal ones are presented for various charge diameters and lengths using explosives of widely different reaction zone lengths. These pressures were found to correspond to the Chapman-Jouguet value of the detonation pressure calculated from thermohydrodynamic theory.
