Abstract: In order to describe the mechanical properties of cord-rubber tire cornering accurately, based on unidirectional fiber reinforced continuum mechanics, an anisotropic hyperelastic constitutive model of cord-rubber composite is presented, which can be used to simulate and analyze tire cornering. The strain energy is decoupled into the strain energy of rubber matrix, the tensile strain energy of cord and the angular shear strain energy between rubber and cord. The model parameters are calibrated based on the experimental data, and the calibrated anisotropic hyperelastic constitutive model is applied to tire grounding and cornering analysis. It provides an important research basis for the development of anisotropic hyperelastic composites constitutive model and high precision cord-rubber tire model.

Key words: cord-rubber, composite, hyperelasticity, constitutive model, tire cornering
