Interaction of convergent shocks in condensed media

Loading of cylindrical specimens by sliding detonation waves is used in the case of explosive pressing and compressing of substances in conservation ampoules. A convergent conical wave is formed in the specimens in such a loading method, and a Mach disc at the cone apex sometimes results. Formationof the Mach disc was observed in Plexiglas, glass, water, aluminum, and NiO and NaCI powders [1-3]. The build-up of a stationary wave configuration being propagated along the axis of symmetry at the shell detonation velocity Do occurred during a certain time in the substances listed. The detonation wave energyis used as an instrument to produce the necessary states in the substances in all the cases mentioned.
