Numerical modeling of TATB shock-wave heating

A model of shock-wave heating of condensed high-explosives (HE) in which a refined dependence of the heat capacity of an HE on temperature is used and the effect of the initial density of the HE is taken into account is given. The dependences of HE (TNT, PETN, and TATB) heating on pressure in the shock-wave front are calculated. Modeling of TATB heating is of interest for understanding the shock-wave detonation initiation, including the dependence of the shock-wave sensitivity on the initial density and temperature of an HE.
