Review of a Unified Elastic—Viscoplastic Theory

  • Chapter
Unified Constitutive Equations for Creep and Plasticity

Abstract

Although inelastic response of solid materials at low stress levels has been observed and measured for over a century and a half (an account of the early work is given by Bell1), engineering thinking on material behavior has been dominated by the considerable success of the classical elastic and plastic theories. In contrast, the work on ‘dislocation dynamics’ in the 1950s and early 1960s by Johnston and Gilman2,3 and by Hahn4 and others was based on the concept of considering both elastic and plastic deformations to be generally non-zero at all stages of loading. Those formulations were one-dimensional and restricted to simple loading histories such as uniaxial extension and creep. One of the main interests in those studies was to obtain the form of the equations and the material constants from measurements of microstructural quantities.
