Abstract

The initiation of chemical reaction in explosive crystals during shock or impact is shown to be a solid state, quantum mechanical, process not accessible by a classical continuum approach. The process by which dislocations move in a solid is analyzed in terms of quantum mechanical tunneling. The motion of these dislocations significantly perturbs the lattice and creates phonons which, for low dislocation velocities can cause local ignition sites and for high dislocation velocities, can have energies sufficient to directly pump the internal vibrational modes of the explosive molecules and cause rapid molecular dissociation.

9. For the explosives PETN, TNT and TATB the shear moduli are approximately 5, 2 and 1 × 1010 dynes/cm2 respectively. A measure of their sensitivity can be had from the drop height from which a 2.5 kg mass will cause ignition in 35 mg samples in 50 % of the impacts. For these materials H50 is approximately 12, 70 and ≥ 300 cm respectively. For other materials the agreement is not as good, but the trend is well established.Google Scholar
