• TITLE: On the Definition of State Variables for an Internal State Variable Constitutive Model Describing Metal Deformation

  AUTHORS: Paul S. Follansbee

  KEYWORDS: Consitutive Modeling, Internal State Variable, Metal Deformation, Ideal Gas Law, Path Dependence

  JOURNAL NAME: Materials Sciences and Applications, Vol.5 No.8, June 30, 2014

  ABSTRACT: The quest for an internal state variable constitutive model describing metal deformation is reviewed. First, analogy is drawn between a deformation model and the Ideal Gas Law. The use of strain as a variable in deformation models is discussed, and whether strain serves as an internal state variable is considered. A simple experiment that demonstrated path dependence in copper is described. The importance of defining appropriate internal state variables for a constitutive law relates to the ability to accurately model temperature and strain-rate dependencies in deformation simulations.
