The Rose–Vinet equation of state are a set of equations used to describe the equation of state of solid objects. It is an modification of the Birch–Murnaghan equation of state. The initial paper discusses how the equation only depends on four inputs: the isothermal bulk modulus
Let the cube root of the specific volume be
then the equation of state is:
A similar equation was published by Stacey et al. in 1981.
