The Department of Defense (DOD) is seeking proposals for the topic "Understanding Fragment Impact on Responding Surfaces" as part of their SBIR 24.2 Annual solicitation. The research focuses on developing techniques for characterizing dust and debris generated from fragment impacts on responding structures, such as concrete walls. The goal is to understand the impact, fragment-structure interaction, and response, including ejected dust and debris. The research will involve developing new diagnostics, experimental techniques, and modeling to determine the amount of dust and debris generated in weapon strike scenarios. The project will be conducted in three phases: Phase I will involve initial experiments and modeling, Phase II will develop a prototype modeling program, and Phase III will include full-scale tests and model predictions. The research will have applications in the defense sector and will contribute to understanding the effect of dust and debris on late-time chemistry. The solicitation is open until June 12, 2024, and more information can be found on the DOD SBIR website.
