In the case of porous material for a single element, a number of EOS are available in the literature based on work by McQueen and Marsh,5 Herrmann,6 and Salvadori et al.7 Here a “snow plow” model, which neglects the compaction process, was used for porous materials with an assumption of the porosity being removed at a very low stress. Dijken and De Hossen8 gave different methods for Hugoniot curves for normal and anomalous cases based on the assumption that a powder at zero pressure from V00 (the specific volume for a porous material) to V0 (the specific volume for a solid material) does not alter the internal energy. Oh and Persson9 derived eight equations for porous materials using the linear relationship between the shock wave velocity and the particle velocity. Simons and Legner10 obtained the Hugoniot pressure in terms of the cold pressure, energy, and density for a porous material. Wu and Jing and colleagues11–13 and Boshoff-Mostert and Viljoen14 derived an alternative equation of state that has the same form as the Mie-Gru¨neisen EOS by using the specific enthalpy. For a solid multi-component mixture, an important acknowledged contribution is the so-called zero temperature mixture theory recommended by Meyers,15 and McQueen et al.,16 which eliminates the temperature effect of different components. Such a theory was used to calculate the 0 K isotherm for two constituents by using mass averages of the specific volume, the cold internal energy, and the Gru¨neisen coefficient. |
