A linear theory of thermochemical equilibrium

Many multicomponent solids can be represented by a continuum model. On this basis a thermodynamic theory of multicomponent stressed solids has been constructed.

After linearisation, the necessary equations for equilibrium can be separated into purely elastic and purely chemical equations. In particular, the usual Hooke's law coefficients are replaced by new open system coefficients. All the parameters of these equations can be computed from standard measurements. Examples showing the use of these formulae are presented.
