Low Order Explosive Response
Abstract
This program is devoted to increasing the level of understanding for non-detonative explosive reactions that are associated with main charge attack. A second goal is to develop the ability to predict the outcome of a main charge disruption procedure and to develop better tools for main charge attack. To achieve these goals, a basic understanding of the phenomenology of non-detonative reactions is being explored. A promising method for understanding non-detonative reactions is to explore the phenomenology with both macroscopic and microscopic approaches. The non-detonative reaction observed in testing for the EOD Main Charge Disruption (MCD) acquisition program indicated that the target's explosive fill, size, and level of confinement are important in determining the final outcome of the event, i.e., the reaction violence and effects experienced by the surrounding environment. In addition, the size, shape, material properties and velocity of the penetrators also influence the outcome. The macroscopic objective of this effort is to quantify the interaction between the above parameters and understand their effect on reaction violence of the main charge. The microscopic approach will explore the detailed effects associated with the explosive fill. Subject areas include shear heating, growth from burn to detonation, material properties, effects of porosity, crystal morphology and rapid phase change effects on initiation and growth. Microscopic analysis will consist of tube tests, activator punch tests, closed bomb tests, special material properties evaluations, and other experiments yet to be determined that will ultimately characterize explosives and calibrate models for predictions of nondetonative reaction outcomes.
