Abstract
Large-scale penetrating munitions are subjected to extreme loading conditions during operational use. Development of these munitions require a significant amount of testing which can be expensive. Much of that cost can be offset through the use of macro-scale models. However, a key aspect of these munitions is the mechanical and chemical response of the composite high explosive (HE) propulsive materials used within the munitions. It is often difficult to model HE materials on the macroscale as a majority of their properties are dependent on the micro-scale. Corvid proposes utilizing the existing Coupled Damage and Reaction (CDAR) reactive burn model to model HE materials on the macro-scale. The CDAR model is able to predict and evolve microstructural damage due to shock and shear loading and is able to interpret damage to determine the initiation, deflagration and detonation behavior of composite HE materials. Corvid also proposes on improving the CDAR development process for specific materials by directly informing the mathematical formations for the microstructural mechanical response within CDAR with Molecular Dynamics (MD) instead of extensive and expensive material characterization. MD is an atomistic simulation method which can directly calculate properties of interest on the micro-scale.
