This paper is concerned with the formulation of a thermodynamic strain-time function for a 2-phase material when subjected to a constant stress in an isothermal temperature field.
It is shown on basis of irreversible thermodynamics that the stress-deformation relation of such systems is of the same mathematical form as the relation obtained from a simple rheological model described in an earlier publication. A correspondence is established between the phenomenological coefficients contained in the thermodynamic function and the structural parameters employed in the mechanical model.
