MEASUREMENT OF THE GRUENEISEN PARAMETER AND THE INTERNAL ENERGY DEPENDENCE OF THE SOLID EQUATION OF STATE FOR ALUMINUM AND TEFLON
Abstract
Experimental measurements of the solid state equation of state of aluminum and Teflon, including the internal energy dependence, were made. The data for aluminum mesh well with the data of other investigators. Using the aluminum data, it was found that for initial aluminum densities of 1.36, 1.60, and 1.82 gms/cc, the thermal internal energy, E sub th, is dependent only on the product VP sub th where V is the specific volume and P sub th is the thermal pressure. The Grueneisen parameter was found to be given by 100 / (39.9 + 0 0. 284 VP sub th) with VP sub th in (cu cm kilobars)/gm. At VP sub th = 0, the Grueneisen parameter = 2.5. The solid Hugoniot for Teflon was found to mesh well with lower pressure measurements by other investigators. The scatter in the porous Teflon samples was too large and the data were too limited to permit evaluation of the Grueneisen parameter.
