Abstract
MECHANICAL initiation of fast reactions in solids can be achieved by various methods: impact1,2, friction3, and shock4. Although it is now generally accepted that the initiation starts with the degradation of mechanical energy to heat, the precise mechanisms by which the energy conversion takes place are not understood clearly. I am concerned here with the initiation mechanism in a column of a compacted solid primary explosive when stabbed with a hard small angle metallic conical striker, which I show to be frictional. A model is presented, which, for the first time, gives a quantitative estimate of the maximum temperature rise generated during the impact.
