CLOSE-IN SHOCK STUDIES

Abstract

Three measures of shock pressure and wave shape were made in the 1-to-10 kilobar pressure region resulting from the detonation of a 20-ton TNT charge on a limestone surface. Results influenced by the presence of a large electrical disturbance after zero time, indicates stress levelof 7.0 + or - 1, 5.75 + or - 1.5 and 4.0 + or - 1 kilobars at ranges of 3.04, 3.96 and 5.18 meters respectively. Hugoniot equation-of-state measurements on the limestone material permitted preshot calculation of the pressure levels as a function of distance from the charge and indicated the likely formation of a two-wave shock structure.
