Abstract

In the paper a thermomechanical framework for modelling elasto-plastic damaged materials is presented. Basic assumptions and concepts are given, leading to formulation of constitutive equations using two potentials only: Helmholtz free energy and dissipation potential. Consecutive steps of the procedure are shown for simplified one-dimensional case, followed by three-dimensional example concerning Beltrami-Michell failure condition.
