Dynamic Materials and Interactions

See opportunist here.

The objective of the Dynamic Materials and Interactions portfolio is to develop fundamental scientific knowledge of the dynamic chemistry and physics of complex materials, particularly energetic materials. The portfoliofocuses on energetic materials science and shock physics of heterogeneousmaterials. Research supported by this portfolio seeks to discover, characterize, and leverage (1) fundamental chemistry, physics, and materials science associated with energetic materials; and (2) fundamental shock physics andmaterials science associated with complex, heterogeneous materials. The research will be accomplished through a balanced mixture of experimental, numerical, and theoretical efforts. This is required for revolutionary advancements in future Air Force weapons and propulsion capabilities including increased energy density and survivability in harsh environments. 

Basic Research Objectives:
Research proposals are sought in all aspects of the chemistry and physics of energetic materials with particular emphasis placed on chemistry-microstructure relationships and the exploitation of fundamental shock physics in heterogeneous materials. Efforts that leverage recent breakthroughs in other scientific disciplines to foster rapid research advancements are also encouraged. Topics of interest include, but are not limited to, the following:
– Mesoscale experiments, and associated models, to understand initiation in energetic materials;
– Predictive processing-structure-property relationships in energetic materials, including reactive materials by design;
– Detonation physics, particularly the steady state reacting front propagating in energetic materials;
– High strain rate and shock response of polymers, composites, and geologicmaterials;
– Shock loading and mechanical response of energetic crystals;
– High energy density materials that overcome the CHNO limitations, including scale-up techniques required for gram-scale characterization of materials;
– Bridging length scales in energetic and other heterogeneous materials.
Energetic materials research is critical to the development of next-generation Air Force weapon capabilities. The energy content and sensitivity of these systems are influenced by the energetic materials utilized. Research areas of interest emphasize the characterization, prediction, and control of critical phenomena which will provide the scientific foundation for game-changing advancements in munitions development and propulsion.
