Modeling HE systems using DSD

PDF Version Also Available for Download.

Description

As a high explosive (HE) ages, those properties of the HE dependent on its global energy-release rate (e.g. shock initiation and detonation propagation speed) are the most likely to be affected. Similarly, any HE replacement will bring with it changes in these same reaction rate dependent characteristics of the HE, in that the new material will not be identical to that being replaced. In this paper the authors describe how detonation shock dynamics (DSD) theory can be used to model how changes in the energy-release rate (as they are embodied in the HE`s detonation speed vs curvature relation) influence the ... continued below
