Munition Effectiveness Modeling and Technology Integration Research

A 24-month Phase II project is proposed to develop and implement models that capture the fidelity of high fidelity physics-based (HFPB) models in a fast-running format. It is anticipated that such models will be incorporated in certain modules of theModular Effectiveness/Vulnerability Assessment (MEVA) code developed for and currently used by the Air Force for assessing munitions effectiveness and target vulnerability. Current engineering models employ resistance functions and/or regression analysisin ways that are unnecessarily restrictive, thereby losing the fidelity inherent in HFPB models. Generalization of these accepted techniques offers the means of over coming restrictions that have limited both the fidelity and utility of conventionalengineering/fast-running models. The new modeling techniques incorporating higher fidelity physics, enhanced response/damage visualization, and improved stochastic modeling have been demonstrated.
