This Phase II STTR proposal will develop a computational tool for state-of-the-art computational modeling of multi-scale thermo-mechanics of heterogeneous energetic materials. The proposal will bring together researchers with long-standing expertise in flow software and physical modeling of high-speed reactive multi-material flows to work on further developing a cutting-edge computing tool called SCIMITAR3D. Spring-boarding off Phase I work, this work will lead to the ability to quantify the relationship between explosive sensitivity and meso-structural parameters such as energetic crystal size and shape and void/defect distributions. Macro-scale and meso-scale analysis will be performed and algorithms to bridge scales using metamodels will be developed. Techniques to simulate damage evolution in the meso-structures subject to loading will be incorporated. The computer code will be provided with a user-friendly graphical user interface to facilitate ease of use and visualization. The proposed Phase II work will lead to a powerful software that can be employed in design of explosive devices that use energetic materials.
