On the full coupling between thermo-plasticity and thermo-damage in thermodynamic modeling of dissipative materials

The phenomenological model of dissipative material in the small strain range is developed in the framework of thermodynamics of irreversible processes with internal state variables and local state method. The possibilities of the model are illustrated in the example of thermo-elastic–plastic damage material. Particular emphasis is put on including in the description of the full coupling between plasticity and damage in nonisothermal conditions. The consequences of thermal-plastic-damage coupling in consistency conditions and loading/unloading conditions are studied in detail.
