Elastomers are viscoelastic materials and their properties significantly depend on the loading rate. The actual stress experienced by these materials is the sum of equilibrium and dissipative (inelastic) terms. At very low loading rates we can eliminate the significant influence of time effects and model the material as hyperelastic. In this paper, the features of the experimental determination and subsequent mathematical description of equilibrium stresses are considered. Verification of the proposed equations has been carried out for a series of experiments - cyclic uniaxial tests of samples of materials on the basis of the same matrix, but with different filler contents and under different maximum degrees of deformation.
