Abstrakt: CREST is an entropy-dependent reactive burn model that has had considerable success in modeling a wide range of shock initiation and detonation behavior in explosives. This paper describes the development and initial testing of a CREST model for the HMX-based explosive LX-14, for which a suite of gas-gun data has become available. The new model has been calibrated to a sub-set of the available data using a semi-automatic method consistent with other recent CREST models, and the fit to the calibration data for LX-14 is universally good. It is shown that CREST accurately predicts the behavior of nominal-density LX-14 in experiments but, consistent with other reactive burn models, it fails to match the low-density gas-gun data. Possible ways to improve the reaction rate in future are discussed. [ABSTRACT FROM AUTHOR]
