Theory of Equations of State: Elastic-Plastic Effects 2

Abstract

After a brief review of the history of material failure studies and of measurements of stored energy in plastically deformed bodies, energy and stress and strain relations are developed for both elastic and plastic deformation in uniaxial strain. The physical effects of plastic deformation are discussed and foundations are laid for thermodynamic calculations of plastically deformed materials. Calculations of both thermodynamic and mechanical parameters are described for uniaxial strain with and without energy storage in internal strains. Conditions of uniaxial strain are found to yield new thermodynamic relations which are useful for synthesizing constitutive relations.
