Abstract: The results of analyzing experimental data on the conditions for initiation of explosive transformation in phlegmatized HMX samples on impact with an indenter with a spherical end are presented. It is shown that the conditions for initiation of explosive transformation in a wide range of variation of parameters of the indenter and impact velocities are described by empirical equations that relate the mass-geometric parameters of the projectile with its minimum velocity, thereby initiating the explosive transformation. The resulting dependences can be used for practically analyzing the outcomes of the impact on an explosive composition, in the construction of adequate physical models of initiation, and their verification.
Keywords: indenter, spherical end, phlegmatized HMX, initiation, explosive transformation.
