Insensitive Munitions Modeling Improvement Efforts
Abstract
Mil-STD 2105C and numerous standardization agreements (STANAGs) outline the various Insensitive Munitions (IM) threats that are designed to simulate the hazards munitions commonly exposed to on the modern battlefield. These threats include sympathetic detonation, shaped charge jet impact, bullet and fragment impact, and slow and fast cook-off. The asymmetric nature of current and likely future conflicts dictates that ordnance designers attempt to incorporate improvements in IM development as early as possible not only to increase the safety and value offered to the war fighter but also to minimize the expense and that it takes to deliver these solutions to the field. One of the most promising techniques that engineers and scientists within the U.S. Department of Defense (DoD) are employing to help to achieve IM performance enhancement is the application of advanced multi-physics modeling programs. These programs account for key aspects of the relevant phenomena, including but not limited to shock physics, heat transfer, chemistry, and detonation. Designers these programs to model scenarios involving the response of confined high explosive warheads or energetic devices to the various external stimuli outlined in the aforementioned standards. Modeling these scenarios is highly desirable as it allows the designer to iteratively interrogate many what if scenarios before ever having to produce test hardware, with obvious beneficial impacts on cost, schedule, and performance.
