Abstract:
The action of shock-wave loading on specimens of an OTK-90 explosive composition is studied. The limiting levels of loading that correspond to the initial stage of explosive conversion of the specimens impacted by steel plates of different thickness are determined. The limiting resistance of the specimens subjected to the gliding detonation of a TP-83 plastic explosive through a polyurethane-foam layer and also to the gliding and normal detonations of a NIL-1 low-density explosive is examined. It is shown that the boundaries of the transition from the purely mechanical failure of OTK-90 to a mechanochemical reaction that were obtained by different methods of shock-wave loading agree well.
