Abstract:
The modified equation of state is proposed for the calculation of thermodynamically equilibrium model TEС2 to improve the reliability of the description of thermodynamic parameters of shock-wave loading of pure materials and heterogeneous mixtures of different porosity. The parameters of the thermally consistent equation of state are determined for copper. A reliable description of the shock-wave loading of copper is obtained for a small number of fitting parameters determined by the experimental data. The thermodynamic parameters for copper of different porosity are modeled, the compression and temperature values along the shock adiabate are determined; the heat capacity value along the normal isobar is calculated. The results of calculations are compared with the known experimental results of different authors.
