Gibbs free energy stability
WebGibbs originally called it available energy and that is a good term because it is the energy associated with a chemical reaction that is available (or you could say free) to do work, assuming constant T and P. Webunder constant temperature (isothermal stability) and constant total entropy of the body (adiabatic stability), using the Helmholtz free energy in the rst case, and the internal energy in the second case. They extended the Gibbs analysis by specifying the boundary conditions to be either the prescribed surface displacements or the
