Overview of Recent Research Efforts in Shock Initiaiton of Energetic Materials

Shock initiation experiments using energetic materials with in-situ gauges to track the process of the initiation front is relatively established and the data obtained facilitates the calibration of various models. In the recent decade, advancements have extended the technique into the areas of studying increased porosity for a variety of energetic materials as well as utilizing multiple or thin-pulse shocks to study kinetic effects in Insensitive High Explosives (IHE's). The ability of various models to reproduce the results has also shown advancement. This work will provide a brief history of using the in-situ gauge technique followed by highlights of recent work with porous energetics or utilizing multiple/thin-pulse shocks. A short discussion of modeling advancements with suggestions for future work will also be included. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
