initiationporosityrarefactionrelief waveThe “DaMaGe-Initiated-Reaction” (DMGIR) computational model has been developed to predict the response of high explosives to non-shock mechanical insults. The distinguishing feature of this model is the introduction of a damage variable, which relates the ...
The reflection of a supersonic propellant gas jet always happens during the firing of the weapon system of aircraft. The reflection induces complex non锕憆emixed shock induced combustion. It is of great importance to investigate the initiation mechanism of the combustion in the supersonic jet of ...

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 ...
Streak camera photographs register initiation stages typical for liquid explosives: preliminary luminescence connected to expansion of detonation in shock-compressed substance; narrow zone of bright luminescence caused by overdriven effect; the detonation withdrawal from overdriven regime.Alexander V.
