Mechanism of the thermal ignition of organic explosives by an electron beam

摘要

A numerical simulation of the ignition of organic explosives (PETN, HMX, RDX, TATB) by an electron beam is performed. A criterion for the ignition of energetic materials with a melting point below the ignition temperature is obtained. The results of numerical calculations of the critical energy density of the electron beam are consistent with the criterion of ignition. The calculated critical energy density of PETN ignition is in good agreement with the available experimental data. The most sensitive HE is PETN, whereas the most heat-resistant is TATB.
