Correlation of shock-initiation tests for explosives and propellants
Comparisons among the shock initiation tests most commonly in use for evaluating explosives and propellants reveal a strong correlation of the results. Lagrange hydrodynamic calculations of the tests are employed to establish the precise nature of the correlation, but we also show how relatively simple approximations to the hydrodynamic results can be used to evaluate shock initiation thresholds. The results of this study provide both an equivalence relationship between the standard tests and a basis for evaluating shock initiation thresholds for hazard conditions in general. The correlations are quite reliably applied to propellants and explosives prepared at a near maximum density. Our analysis of available data shows that the correlation for porous materials is still uncertain.
