résumé The objective of this study is to propose a thermo-visco-hyperelastic model capable to predict the self-heating of rubber-type materials under fatigue loading. The model, compatible with the Clausius-Duhem dissipation principle, is based on a Zener rheological representation. Considering the thermo-mechanical coupling a pseudo-potential of dissipation, function of the viscous dilatation tensor, is postulated. The proposed model has been implemented into a finite element code and validated from an experimental database of a typical rubber-type material. The strain-rate and maximal strain effects over the self-heating pending cyclic loading are shown.
