Certain materials, when impacting a target at high velocity will chemically react due to the shock wave passing through them, thereby increasing the damage done by the material. In particular, the reactive materials of interest are capable of acting as both structure and explosive, allowing them to achieve an effect similar to a High Explosive Incindiary (HEI), without the complexity and added mass of fuses. There are a large number of materials/material combinations that could be used in reactive munitions. The purpose of this effort is to determine an efficient analytical characterization methodology that can be validated with a minimal testing effort. The data resulting from implementing this methodology for many materials would allow the development of a parametric design tool for designing effective reactive munitions using realistic damage metrics. The realistic damage data for the parametric tool could be obtained from high fidelity simulation and a minimal amount of expensive testing, using the characterization tests described here, for validation purposes. This work presents a method for characterizing, modeling, and then validating the equation of state models of reactive materials in general and demonstrate this process specifically for an aluminum-polytetrafluoroethylene (PTFE) mixture that has been shown in previous tests to be a promising example of this kind of enhanced-lethality projectile. In this thesis a methodology is described to create a reactive material equation of state (EOS) for use in LS-DYNA which is then demonstrated by simulating characterization tests that would aid in the validation of the EOS and a realistic damage test for which test data is provided for comparison.
