EQUATION OF STATE FOR CALCULATING TEMPERATURE OF MATERIAL IN EXPLOSIVE PROCESSING

An equation of state with potential and thermal pressure components has been obtained which makes it possible to calculate the temperature of a condensed medium at high energy densities. The derivation of the equation of state is based on the concepts of a covolume and a free volume for thermal motion of particles and universality of the relationship between the pressure behind the shock-wave front and the potential pressure component. For the proposed equation of state, it is necessary to know only the shock adiabat of the medium. A comparison has been made of calculation results and experimental data for the temperature behind the shock-wave front in elementary substances and chemical compounds. The obtained equation of state can be of use in practical applications and in shock-wave experiments.
