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

Birchall, T.J.; Osman, A.S.

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.
