摘      要：This paper establishes an empirical formula to predict the strain amplitude effect.A viscoelastic constitutive model-the superposition of a hyperelastic model and a viscoelastic model-is constructed based on the laws of thermodynamics.The Mooney Rivlin model and the Prony series are employed for uniaxial tension testing.The empirical formula is derived using a hysteresis loop;it obtains results that are in agreement with the experimental results of dynamic mechanical analysis(DMA).The empirical formula proposed in this paper has certain accuracy in predicting the dynamic modulus under different strain amplitudes.
