If * * f is the change per unit volume in Gibbs function caused by the shear field at constant P and T , and �r is the density of the fluid , then the total potential_energy of the system above the reference height is * * f .

The relation between osmotic_pressure and the Gibbs function may also be developed in an analogous way .

The concept of the strain energy as a Gibbs function difference * * f and exerting a force normal to the shearing face is compatible with the information obtained from optical birefringence studies of fluids undergoing shear .
