Presentation of a general equation of state that provides a suitable description of the thermodynamic behavior of metals over a very wide range of temperature and compression. The thermodynamic dependence of pressure and specific internal energy upon temperature and compression is described by equations having coefficients that can be related to measured or calculated physical variables. This makes such a formulation useful in assaying the effect of the parametric variation of the equation of state on hydrodynamic calculations. A description of the physical basis of the terms in the equation of state is given. The calculation of the specific entropy is reviewed and a method of calculation of Hugoniot points is presented. A summary of the program written for machine calculation of the equation of state is given, along with the appropriate input instructions.
