The goal of the paper is to outline the major steps of thermomechanical constitutive modelling with emphasis on incorporation of non-associative evolution laws. A brief description of the main assumptions and general equations are given. Then two examples are presented, both resulting in Beltrami-Michell failure condition, but differing in dissipation potential. The first example couples effects of plasticity and damage, while the second separates the phenomena. Some comments are given on basic technicalities in modelling.
