Ignition of Crystalline Explosives

A physicomathematical model of ignition based on the model of an anisotropic medium with damage was proposed to study the mutual effect of the solid–state reaction and mechanical processes involved in the ignition of crystalline explosives. In the case of a hexagonal crystal, the model reduces to a coupled one–dimensional model of ignition with a wider range of parameters than that in the model of ignition of isotropic material. For example, the factor of coupling of the strain and temperature fields can now take negative values. Examples of numerical solution of the ignition problem are given for various particular cases.
