THE NORMALIZED DEPENDENCE OF PETN - V EXPLOSIVE DECOMPOSITION CRITERION AT THE INITIATION BY LASER PULSES OF DIFFERENT DURATIONS

A hypothesis of the universal curve existence for the initiation criterion independent on the pulse duration was suggested on the basis of the calculated dependencies of critical energy density of PETN based composites containing metal nanoparticles of variable radii. Introduction of the relative coordinates allowed us to describe the initiation criterion dependence on the radius at pulse durations of 12 ns and 20 ns with one curve. The accuracy value was more than 99.999%, which led to the conclusion that the universal curve exists.
