Theoretical calculations of wall pressures and elastic wave radiations from high-explosive detonations in spherical cavities in salt are compared with close-in experimental results from the Cowboy program. Spherical charges of Pelletol ranging from 20 to 2000 pounds were detonated in spherical cavities 12 and 30 feet in diameter. The elastic wave and the wall-pressure results were found to be sensitive to the explosive detonation details. New ways are suggested for correlating such quantities as explosive and radiated energies, peak values of particle displacement, velocity, acceleration, and radial stress. This correlation procedure can be useful in scaling peak particle velocities from cavity or uncoupled explosions; it is demonstrated for the Cowboy results.
