Shear instability at the “explosion product–metal” interface for sliding detonation of an explosive charge

Abstract:
Periodic perturbations at the “explosion product–metal” interface were studied experimentally. Experiments were performed for both spherical and plane geometry. Critical conditions of wave formation (detonation velocity of an explosive charge $D\ge6.9$ mm/$\mu$sec) are determined, and an explanation of this effect is given. It is found experimentally that a dynamic pulse causes intense plastic strains at the “explosion products–metal” interface, leading to thermal softening of the steel boundary layer. In this layer, Kelvin–Helmholtz instability occurs. Calculation-analytical estimates of the critical boundary unstable wavelength agree satisfactorily with experimental results.
