This article attempts to determine the minimal (critical) energy for excitation of octogene detonation and the selection of the optimal mass of the impacting plate. The process of explosive decomposition of detonating high explosives (HE) and powders is considered as a thermal explosion which is preceded by adiabatic compression of the specimen. The critical energy of initiation is determined as the minimal energy that is sufficient to excite a thermal explosion that goes over into detonation. The explosive decomposition of octogene was excited by the impact of steel plates. The results indicate that the specific volume of the compressed specimen layer varies insignificantly for different impacting plate masses and velocities and minimal initiation energies. It is determined that the optimal mass of the impacting initiating plate must be selected in determining the critical initiation energy of the substance being investigated.
