| Popis: | The paper is devoted to the determining the conditions of realization of the chain, chain-thermal and thermal mechanisms of energetic materials explosion decomposition. The following data were used: 1) the dependence of decomposition rate on the inverse temperature of the sample with the definition of the effective activation energy of the process; 2) the dependence of the critical energy density of the explosive decomposition initiation on the pulse duration. The calculations were made for silver azide initiated by pulse radiation of different duration. The dependencies of the critical energy density on the pulse duration for the different values of recombination constants were examined. The research showed that the realization of either chain or thermal mechanism is defined by producing the exposure duration and the rate of recombination constant. |
