A shock initiation model for fine-grained hexanitrostilbene
Conference

OSTI ID:5860440
An established body of data indicates that very fine-grained hexanitrostilbene (HNS), when pressed to 92% of crystal density, exhibits shock initiation characteristics unlike those typical of porous, granular explosives. That is, a progressive buildup towards detonation from an initial shock by hot spot formation and growth processes is not observed. Instead, this particular HNS exhibits shock initiation characteristics normally associated with homogeneous explosives (e.g., the formation of a superdetonation wave after an initial shock has been introduced). In the present work, a comprehensive effort has been made to develop a predictive model for shock initiation in this material. This model is based on a theory of homogeneous reactive mixtures, and includes a refined equation of state for porous HNS reactant and a JWL equation of state for gaseous reaction products. The model has been incorporated into wave propagation codes, and comparisons with available initiation data are made. 22 refs., 8 figs.
