Abstract
A heuristic model has been formulated to calculate the pressure behind the shock wave front in condensed matter. The model is based on the empirical relationship between the total pressure and the product of the potential pressure component by the degree of shock compression. The model is supported by molecular dynamics calculations of the thermodynamic state of shock-compressed condensed matter and by comparison with experimental data on the isothermal and isentropic compression of iron.
