Equation of State of Solids.

Abstract

The report describes a program for computing equation of state parameters for a material which undergoes a phase transition, either rate-dependent or reversible. The FORTRAN program is described in detail and a sample calculation is made for iron. A modification is described which makes it possible to compute the rarefaction shock arising from a phase transition. This too is computed for iron with and without rate-dependence in the transition. Next, a FORTRAN program is described for deriving crystalline elastic constants from sonic measurements at high pressure; it is capable of obtaining explicit temperature dependence if measurements are made at three temperatures. It is applied to data from calcite. Finally a theoretical equation of state is described for solid iron. (Author)
