Equation of State for Tantalum at High Pressures in Waves of Shock Compression and Isentropic Expansion
A simple analytical function of pressure versus specific volume and specific internal energy is proposed for describing thermodynamic properties of tantalum in the region of high pressures in the shock-compression and isentropic-expansion waves. On the basis of this equation of state, thermodynamic characteristics of tantalum are calculated in a wide range of degrees of compression and heating. The results of the calculations are compared to the available tantalum data of experiments with shock and centered simple waves. The above equation of state can be used to simulate adiabatic wave processes at high energy densities.
