Equation of State Modeling for Porous Materials

This chapter describes the theoretical equations of state (EOSs) for porous and granular materials. In principle the EOS for a porous/granular material is identical to the EOS for the equivalent non-porous material; however, the requirement that the EOS must provide a realistic model of the material in its porous/granular state presents additional challenges. Broadly these challenges are first that the regions of thermodynamic phase space of interest are poorly described by standard wide-ranging EOS models and second, accurate measurement of materials properties that are routinely used to constrain an EOS can be more difficult to obtain. This chapter describes in detail the challenges and methods for EOS generation of porous materials.
