In a number of experiments1–3 carried out to study the effects of shock waves in condensed materials (particularly in chemical explosives), we found evidence for the mechanical fracture of covalent bonds in or very near the shock fronts which produced free atoms and free radicals, as well as other thermally-activated atomic and molecular species. Scrutiny of the streak and framing camera records obtained in these experiments led us, with other analysis, to the formulation of a new concept of the shock initiation of explosives.4,5 To obtain some corroboration of this concept and to elucidate the microscopic processes occurring in the shock, we completed computer modeling and molecular dynamics analysis of the experiments.
