Abstract
In the course of work for the Defense Advanced Research Projects Agency's (DARPA) Adaptive Vehicle Make (AVM) program, we developed bounding and accuracy models for various penetration models. Typically the information that is available includes a penetration model or curve fit that nominally matches the average results over a range of impact conditions, some data showing scatter, and then an idea of what the variations and uncertainties are in input properties for the model, which includes material properties, velocity, and geometry. The desire is to then take this data and develop a bounding model that can run as quickly as the nominal model, and (if possible) is as ``first principles'' as is the original model. A methodology is described for doing so, and we demonstrate the method with three different types of models, the Walker-Anderson penetration model, Walker's fabric perforation model, and a blast model.
