TLDR
An extension of Prager-Ziegler's work-hardening rule for infinitesimal elastic-plastic deformation to a workhardening rules for finite elastic plastic deformation of polycrystalline metals at elevated temperatures is developed in this paper.Abstract:
An extension of Prager-Ziegler's work-hardening rule for infinitesimal elastic-plastic deformation to a work-hardening rule for finite elastic-plastic deformation of polycrystalline metals at elevated temperatures is developed. Attention is given to the development to satisfy certain invariant, continuity and thermodynamic requirements.read more

Coupling Phenomena in Thermoplasticity
TL;DR: In this paper, a general framework is developed for the formulation of a phenomenological theory of large inelastic nonisothermic deformations particularly of elastic-plastic and elastic-viscoplastic bodies.

A large deformation anisotropic thermoviscoplastic constitutive model
TL;DR: In this paper, an anisotropic large deformation thermoviscoplastic constitutive model has been formulated in which flow is regarded as a dissipative process characterized by a "driving energy", a threshold energy, and a retardation time.

Elastic-Plastic Deformation at Finite Strains
TL;DR: In this paper, the authors generalize a previous theory to permit arbitrary deformation histories by considering two coupled thermodynamic systems: one comprising thermo- elasticity at finite strain and the other the irreversible process of dissipation and absorption of plastic work.
Journal ArticleDOI
Thermodynamics with Internal State Variables
TL;DR: In this paper, the authors study the thermodynamics of nonlinear materials with internal state variables whose temporal evolution is governed by ordinary differential equations, and employ a method developed by Coleman and Noll to find the general restrictions which the Clausius-Duhem inequality places on response functions.

Inelastic constitutive relations for solids: An internal-variable theory and its application to metal plasticity
TL;DR: In this article, the theoretical foundations of constitutive relations at finite strain for a class of solids exhibiting inelasticity as a consequence of specific structural rearrangements, on the microscale, of constituent elements of material.

TL;DR: In this article, an isotropic elastic-plastic continuum theory was proposed for large deformation elasticity, which is a special case of the theory of elastic-perfectly plastic continuum.
