In order to rectify the excessive stiffness of the [[Murnaghan equation of state]] as well as represent the exponential dependence of the repulsion as solid undergoes strong compression, Vinet proposed an equation of state (without mentioning that it had been used previously for instance by F. D. Stacey, B. J. Brennan and R. D. Irvine in "Finite strain theores and comparison with seismological data", Geophysical Surveys, 4, 189-232 (1989)) as either the '''Vinet equation of state''' or '''Universal equation of state'''<ref>[http://dx.doi.org/10.1103/PhysRevB.35.1945 Pascal Vinet, John R. Smith, John Ferrante and James H. Rose "Temperature effects on the universal equation of state of solids", Physical Review B '''35''' pp. 1945-1953 (1987)]</ref>. The equation of state was formulated so that one form could represent all solids in reasonably wide ranches of pressure, depending only on data for the calibration point.
