On the Mechanism of Molecular Condensed EMs Transformation under the Effect of Shock and Detonation Waves

Dremin A. N.

Central European Journal of Energetic Materials

2008

Vol. 5, nr 1

31-44

Considerations based on available experimental data on regularities of molecular condensed EMs decomposition under the effect of shock waves of different intensities are presented. It follows from the considerations that there exist shock wave pressures p* typical for each charge (for TNT charges p* ~ 12 GPa) and the charges’ initial density ?0* (for TNT 0* ~ 1.40 g/cm3) such that at larger pressure and density EMs' decomposition proceeds according to the homogeneous mechanism (does not depend on the charge structure: initial density, size and structure of explosive particles, explosive state-liquid or solid, …) and at lower pressure and density – according to the hot spots mechanism (depends on the charge structure).
