| Popis: | A new constitutive equation for rubber-like materials model was proposed. The model is based on the Arruda-Boyce (AB) 8-chain non-Gaussian molecular network to which two new terms were added. Taking into account the effects of molecular chain entanglement and the topological constraint on the transverse motions of a single chain, the new added components combine the phenomenological theory of elasticity for rubber vulcanizates at large deformation and the tube theory for topological constraint. The new model contains five parameters which are obtained by fitting the uniaxial Treloar extension data, the predictions from the proposed model for equi-biaxial extension and pure shear are in good agreement with test data. Moreover, compared with some available models, the proposed model is more suitable for characterization of the uniaxial tension mechanical behavior of carbon black particles filled rubber material. |
