Abstract:

Currently, there is a considerable gap in the level of theoretical understanding of the mechanisms triggering energy release between liquid and solid energeticexplosive materials. Although adiabatic impact-induced triggering in solid energetic explosive materials is still treated similarly to liquid, there are qualitative differences in the impact-induced triggering of liquids and solids. In this report, we discuss our recent results related to the impact-induced triggering in solid energetic materials.
