Revisiting the deformation mechanisms in rubbers from surface calorimetry-based energy characterization
Résumé
Complete energy balances carried out during cyclic deformation of rubbers (especially filled rubbers) show that viscosity is not systematically the preponderant contribution to the hysteresis loop: the mechanical energy brought to the material is not entirely dissipated into heat but can be predominantly used by the material to change its microstructure. A ratio in terms of energy has been defined to fully characterize the energetic behaviour of rubbers and opens new way of interpretation of the resistance of rubbers through their ability to store mechanical energy.
