Paper Abstract

Gram-size, spherical high-explosive charges were used to produce craters in a variety of cratering media under carefully controlled laboratory conditions. Rotating prism cameras with framing rates up to 7500 pps were used to observe the formation of the crater. and the debris plumes produced by detonation of these charges. Analysis of the high-speed films obtained with these cameras resulted in the measurement of particle displacement, of dynamic strain, and of changes in density of the cratered medium. Quantitative measurements of the velocity and trajectory of particles in the debris plume were obtained with use of a special lighting technique, a still camera, and a rotary shutter.
