Birch murnaghan equation of state units
WebAn equation of state consists of calculating the total energy (E) as a function of the unit cell volume (V). The minimal energy is reached at the equilibrium volume. Equivalently, the equilibrium is defined by a vanishing pressure: p = − d E / d V . WebEquationOfState): """ Base class for the isothermal Birch Murnaghan equation of state. This is third order in strain, and has no temperature dependence. However, the shear …
