A linear constitutive rule to simulate the cyclic behavior of viscoelastic material is proposed. It is based on the fractional time-derivatives of the strain and stress. Part 1 paper addresses modeling of the linear behavior and its temperature and frequency sensitivities. The model for the first time utilizes the temperature-frequency equivalency characteristics, inherent in many typical viscoelastic materials. The constants involved in the rule are determined systematical]y from sinusoidal loading experiments. The rule appears to be accurate over the wide range of temperature 0℃ to 40℃ and frequency 0.1Hz to 10Hz or greater. The proposed rule is also compared with the rules using integer time-derivatives, and it has shown advantages such as excellent accuracy, simple modeling scheme, and straight-forward numerical algorithm.
