Abstract: The dynamic compression and localized adiabatic shear in samples of an HMX based explosive using the Hopkinson split bar technique was studied. Experiments to study dynamic compression were performed at strain rates (0.3–2.0) $\cdot$ 10$^3$ s$^{-1}$. Fracture of the explosive samples was found to occur at stresses of 60–80 MPa. The behavior of HMX based samples was also studied in experiments on localized shear at different strain rates (200–2500 s$^{-1}$). The issues of the initiation of explosive transformations under the dynamic loads are discussed.

Keywords: ВВ, explosive, low-velocity impact, dynamic compression, fracture, adiabatic shear, explosive transformation.
