초록정보

It is generally accepted that the shock initiation of heterogeneous explosives begins with the formation of hot spots in the vicinity of microstructural defects such as voids and grain boundaries where there can be significant localized deformation as a result of material viscosity, plastic work, and intergranular friction. We propose a shock initiation model for solid explosives, which is based explicitly on the hot-spot concept. The ignition and growth concept of shock initiation in heterogeneous explosives was incorporated into a special version of the one-dimension Lagrangian hydrodynamic code STEALTH. Arrhenius kinetics using the Kim(4)'s hot-spot temperature is adapted for the ignition process and the growth is treated similarly as Lee and Tarver(2)'s. Results of the model calculations are in good quantitative agreement with recent manganin pressure gage and particle velocity gage measurements of the initiating shock front to detonation in PBX-9404 and TATB.
