SHOCK SENSITIVITY OF LOW DENSITY GRANULAR EXPLOSIVES

The structure of shocks which initiate a detona tion wave in low density granular explosives is discussed. Measurements of shock sensitivity of ammonium perchlorate, PETN, and mixtures of the two are reported. The data are interpreted in terms of temperature of the receiver on the basis of two simpl...

Description
Summary:The structure of shocks which initiate a detona tion wave in low density granular explosives is discussed. Measurements of shock sensitivity of ammonium perchlorate, PETN, and mixtures of the two are reported. The data are interpreted in terms of temperature of the receiver on the basis of two simple models: the equilibrium tempera ture of a locking solid assuming complete compac tion, and the temperature of the interstitial gas at the moment the shock has entered the receiver.
