✦ Synopsis

An analytical equation of state is offered for metals. The form, which arises when the complementary solution to the Gru¨neisen cold curve is mapped on to a term in the universal lattice potential, is expressible completely in terms of the characteristic temperature, , and its derivatives. For one particularly useful special case, the results have been found to match both cold-curve and shock-Hugoniot data for a variety of metals. The equation is of the Gru¨neisen variety, in that the Gru¨neisen parameter is specified as a function of volume only. The equation is able to accurately model the behavior of many materials into the megabar range of pressures.

## Abstract An equation of state for polymer melts has been devised from observation on pressure–volume–temperature data for several thermoplastics. The final equation has the form (P + Π − __mT__ ln (__cV__^\*^)) ln (__cV__^\*^) = __gT__, where __P__ is pressure; __T__, absolute temperature, __V__
