Phenomena in High Explosive Charges Containing Rod‐Shaped Inert Elements

Describing shock wave processes, one typically uses relations derived under the assumption that the wave is plane and propagates in a space that is unbounded in the direction transverse to the front motion. This means that a uniaxial deformation is realized under the shock compression. In practice, specimens and elements of various designs always have finite dimensions, and shock compression can be accompanied by transverse deformations. This is particularly noticeable in the case of shock waves propagation in rods, the transverse dimensions of which are much smaller in comparison to the longitudinal ones. According to modern concepts, the main mechanism for the development and propagation of detonation processes in heterogeneous high explosives is related to the formation and evolution of hot spots caused by a number of microstructural and deformation properties of explosives. These properties are very sensitive to external influences, which in this way can affect the sensitivity of explosives.
