Molecular Dynamics of Nitramines and High Energy Composite Materials.

Abstract

Determination of the pressure-temperature phase diagram of the beta-to-delta polymer conversion of HMX has been completed. Enthalpy, entropy values were determined as was the effect of particle size. Variations in the nature of decomposition were found to be the source of the observed slope breaks and the particle size effect. The mechanism of motion in beta-HMX up to the phase transition temperature was found to involve disruption of the pivoting motion about the most stabilizing intermolecular interaction in HMX.
