Engineering Models of Reactive Munitions and Damage Effects

The objective of this proposal is to formulate an innovative modeling approach for a reactive fragment impact with a target, based on first-order, simplified engineering analysis of key physical and chemical processes. These processes include fragment break-up, energy release rates, energy deposition rates into the target and target failure. The model will relate these processes to practical design parameters such as the properties of the reactive materials, the fragment shape, dimensions and materials of construction, as well as the target parameters. Thus, the model will provide a basis for tailoring the fragment design to obtain controlled fragment break-up and energy release upon impact.
