Description
Summary:A thermodynamic formulation is proposed for deducing 0 K isotherm from shock Hugoniot data. In comparison to previous published thermodynamic approaches, the characteristic of this one is not requiring heat capacity as input and the used values of Grüneisen parameter merely confined to around ambient condition. Therefore, it keeps away from the difficulties in determining reliable heat capacity and Grüneisen parameter at high temperatures by experiments and theories. The predicted 0 K isotherms for seven selected metals and their related parameters of initial densities, initial bulk moduli, and their first pressure derivatives are all in well agreement with available experiments and theoretical estimations.
