Davis EOS and AWSD rate-law calibration for PBX 9012

We will present a full model calibration of the AWSD (Arrhenius Wescott-Stewart-Davis) rate law, and associated Davis reactants and products equations of state for the high explosive, PBX 9012. The reactants and products EOS were calibrated using a combination of experiment, theoretical (density functional theory), and thermochemical data (as calculated with Magpie, LANL’s thermochemical code). The AWSD rate law was calibrated to shock-to-detonation transition embedded-gauge experiments, as well as diameter-effect and front-curvature data. Optimal results will be compared to experimental and theoretical data, and the optimization framework will be briefly discussed.
