ABSTRACT
Initial free-surface velocities imparted by grazing (side-on) detonation waves were surprisingly found to be predictable simply by dividing by 2 those equations previously developed to describe the initial velocity imparted by normal (head-on) impact of detonation waves. Thus, two equations having a change-over point at one specific ratio of plate thickness to charge length (t/L) [charge thickness for side-on] were found to represent and predict the initial free-surface velocity for a range 0.001 < t/L < 10 for both head-on and side-on propulsion. Such a simple relationship for the initial free-surface velocities may imply that a detonation's thin high-pressure zone behaves as if it is a Poisson-like solid.

    In this work we investigate the dynamics of self-sustained detonation waves that have an embedded information boundary such that the dynamics is influenced only by a finite region adjacent to the lead shock. We introduce the boundary of such a domain, which is shown to be the separatrix of the...

    The process of cutoff of low-velocity areas of a shaped-charge jet with the help of a reverse-action shaped charge adjacent to the base of the shaped charge and having an axial channel where the shaped-charge jet passes is considered. The operation of the cutoff device and the shaped charge is...

    A physical model of low-velocity detonation in plasticized HMX is considered. In this model, a low-velocity detonation wave is a combination of a weak leading shock wave and a subsequent compression wave. This combination is formed by the simultaneous effects of energy release and spreading of...
