Abstract
The concept of operational equations of state (EOS) is discussed and illustrated with several examples. We discuss several related concepts: (1) the complete and incomplete equations of state, (2) the skeleton of the equation of state, (3) the thermodynamic degrees of freedom of the EOS. Special emphasis is given to the operational equations of state associated with the data related to isentropic and high-rate (shock-like) loading. We present several novel explicit formulas for the recovery of the complete and incomplete operational equations of state for hydrocode. It is assumed that for the process under study that the substances can be treated as possessing only two thermodynamic degrees of freedom.
