On the formulation of thermodynamically-consistent viscoplastic-damage constitutive models.

Birchall, T. J. and Osman, A. S. (2013) 'On the formulation of thermodynamically-consistent viscoplastic-damage constitutive models.', CM13: International Conference on Computational Mechanics. Durham, UK, 25-27 March 2013.

Abstract

This paper illustrates the formulation of viscoplastic-damage constitutive models using the framework of hyperplasticity. The entire constitutive behaviour is derived from only two scalar potentials; a free energy potential and a dissipation potential. This ensures that the model obeys the laws of thermodynamics.
