Abstract
This report presents the results from a series of 20 experiments in which 100-gram charges of C4 explosive were buried at various depths in Silica 20 sand and detonated. These experiments were conducted with the goal of studying the basic explosion physics of shallow-buried charges, representative of land mines, and to generate a high-quality data set for the validation of computer codes. The data recorded includes overpressures and shock wave time of arrivals in air and in soil. Above ground gauges 30, 70, 110, 150, and 190 cm above the surface of the sand recorded side-on pressure. In-ground gauges at 7.5, 10.0 and 12.5 cm from the bottom of the charge recorded the passage of the shock in that medium. Flash x-ray exposures captured the early soil deformation while a high-speed camera captured the expansion of the detonation products and late ejecta motion. The data is presented in a format suitable for code validation.
