General theory of inelastic media

A general approach [1 - 8] for the construction of the theory of inelastic media is proposed (2001 - 2005). The main attention is given to the clear introduction of basic concepts: strain measures, internal energy, temperature, and chemical potential. Polar and non-polar media are considered. The originality of the suggested approach is in the following. The spatial description is used. The fundamental laws are formulated for the open systems. A new handling of the equation of the balance of energy is given, where the entropy and the chemical potential are introduced by means of purely mechanical arguments. The internal energy is given in a form, at the same time applicable for gaseous, liquid, and solid bodies. Phase transitions in the medium are described without introducing any supplementary conditions; solid-solid phase transition can also be described in these terms. The materials under consideration have a finite tensile strength; this means that the constitutive equations satisfy to the condition of the strong ellipticity.
