WebThe Rose–Vinet equation of state is a set of equations used to describe the equation of state of solid objects. It is a modification of the Birch–Murnaghan equation of state. The initial paper discusses how the equation only depends on four inputs: the isothermal bulk modulus, the derivative of bulk modulus with respect to pressure ′, the volume , and the … WebThe simplest form of the Birch equation has two fixed exponents and one adjustable coefficient. A generalized and modified form of the Birch equation based on the theory of finite strains containing two adjustable parameters was used in the present paper. The Tait equation, also a two-parameter equation of state, has customarily been used to ...
