THERMODYNAMIC FUNDAMENTALS OF RHEOLOGY (TERMODINAMICHESKIYE OSNOVY REOLOGII).
Abstract
A thermodynamic substantiation of rheological relationships is presented. Mechanical and thermal processes in a medium are studied, assuming the smallness of deformations and invariable density of the matter. The form of the most general rheological interrelations is established. The general problems of plasticity, creep, and strain hardening of materials are investigated from the thermodynamic viewpoint. It is established that strain hardening is accompanied by a separate process in the medium and is characterized by parameters which are the tensors of the second rank. Such a representation explains the Bauschinger effect, afteraction, relaxation of the material, the dependence of strain hardening on the rate of inelastic deformations, conversion of a part of the mechanical work into latent strain energy, and initiation of anisotropy.
