“…The theory of Self-Organizing Linkage Patterns (SOLP) explains the Mullins effect as a result of a self-organization process based on the weak physical bonds (Besdo and Ihlemann (2003)). Recently it was demonstrated that this concept also provides explanations for other phenomena of rubber behavior (Wulf and Ihlemann (2011)). Various other concepts have been suggested, for instance slipping of chain molecules or molecule disentanglement.…”

a b s t r a c tThis work focuses on the thermodynamics of pseudo-elastic material models which represent the MULLINS effect. Two established models are analyzed theoretically, their thermomechanical properties are derived, and certain disadvantageous points are identified. These findings are used to deduce an alternative approach to deviate pseudo-elasticity. This is achieved by defining a suitable free energy which imposes conditions on the stress tensor and the dissipation using the CLAUSIUS-DUHEM inequality. The concept of pseudo-elasticity is then generalized to extend arbitrary thermomechanical, even inelastic, material models to allow for softening effects. Under weak assumptions on the softening function the thermomechanical consistency is shown.
