Progress in the field of the science of materials led to increasingly significant and diversified use viscoelastic materials such as elastomers, commonly called rubbers. The latter often represent an alternative to metallic materials, it because of their low mass, reduced facility production costs of working, but also of mechanical dissipation of energy.For that, they are very employed in many industrial sectors. The objective of this work is to validate the rheological model, such as the traditional analog model with the theory of viscoelasticity to envisage the answers of creep and relieving of materials.Consequently, it is necessary to develop an analytical model which can envisage exactly the behavior of the structures of these materials under the effect of creep and relieving.
