Method for studying the decomposition kinetics of an explosive behind a SW front

An experimental procedure is proposed that allows simultaneous measurements of time dependences of pressure and density in the same experiment. The dependences can be used to determine the variation in the phase composition of the material behind the shock front in the coordinates pressure-volume and to calculate the time variation in the degree of decomposition of the explosive after the passage of the shock front. Dependences of the formal kinetics of postshock decomposition were obtained for an explosive composition based on sensitized HMX.
