Abstract
1. The ignition of solid explosives by the heat of dry friction during slipping at a constant velocity of the half-space of an inert material along the half-space of an explosive was considered theoretically. 2. Solid explosives were divided into two groups according to the magnitude of specific friction force. The temperature dependence of the friction force was taken into account. 3. The conjugate thermal problem was reduced to a boundary-value problem, for the solution of which the approximate method of the thermal theory of ignition of condensed explosives was used. 4. The solution obtained permits finding the temperature, time, and heat of ignition as a function of the pressure, velocity, friction coefficient, strength of the explosive, melting point, and thermophysical and kinematic parameters. 5. The results obtained can be used for estimating the sensitivity of solid explosives to mechanical loads.
