Abstract:
      The strain rate-related mechanical behavior model of elastomer materials was studied. The force analysis of elastomer materials under uniaxial tension was carried out to obtain the relationship between stress and strain energy，and the intrinsic time variable of the material was studied on the basis of thermodynamic analysis. The intrinsic time variable was combined with the generalized maxwell model to obtain a model that expressed the viscosity of elastomeric materials，and this model was combined with the Mooney-Rivlin hyperelastic model to establish the strain rate-related mechanical behavior model of elastomeric materials. The analysis showed that the parameters in the model were consistent with the physical facts，and this model had engineering application value in the field of shock absorption and cushioning.
