“…Then, we developed the modified soft-sphere model to properly evaluate the Hugoniot of highly porous materials, as their final shocked states are in the fluid region [29]. In another development, we used the EOS to show that the enthalpy-based approach can be implemented [44] in hydrodynamic simulations to describe shock wave propagation in solid as well as porous materials.…”

A simple equation of state model for metals at high temperature and pressure is described. The model consists of zero-temperature isotherm, thermal ionic components, and thermal electronic components, and is applicable in compressed as well as expanded volume regions. The three components of the model, together with appropriate correction terms, are described in detail using Cu as a prototype example. Shock wave Hugoniot, critical point parameters, liquid–vapor phase diagram, isobaric expansion, etc., are evaluated and compared with experimental data for Cu. The semianalytical model is expected to be useful to prepare extended tables for use in hydrodynamics calculations in high-energy-density physics.

“…Applications of the EOS model to other materials can be easily carried out using the experimental/theoretical values of the parameters [16,33] employed in the different components of the model. A list of these parameters for Cu, Al, Fe, and W is given in our earlier publication [44].…”
