Theoretical and experimental studies have been carried out involving the analysis of the effects of precompression upon the detonation properties of explosives. The experimental results confirm the theoretical prediction that the effects are all attributable to the change in density. Overdriven detonations have also been studied both theoretically and experimentally, and theoretical models have been developed. The influence of powdered metals on the energy released during detonation has been studied theoretically. It has been shown that for small enough particle sizes, contributions to the enhancement of plate acceleration should become observable. Over the range of hydrostatic pressures up to 90,000 psi, the relationship between detonation velocity and charge density has been found to be linear for nitromethane, Composition C-3 and HBX. Author
