Abstract A phenomenological constitutive model for carbon black filled rubber materials is investigated in this paper. Considering the Mooney model cannot describes stress-strain relations of rubber-like materials at large deformation regions, characteristics of the Mooney model is analyzed by using experimental data. The relationship of carbon black content and strain range size of Mooney model accurate characterization of rubber materials is discussed, then the prediction ability of the model account for the stress-strain relations under multiaxial loading conditions and the influence of model parameter are analyzed. Finally, on the basis of Mooney model, a correction term is added, and the amended Mooney model must satisfy the six assumptions proposed by Treloar and Ogden. By comparing with the experimental data, the new model can well describe the rubber material stress-strain relationship of the large deformation stage, and can improve the ability of predicting the complex deformation of the rubber-like materials.
