| Abstract: | The creep tests of viscoelastic material butyl rubber were conducted under the conditions of different temperatures and different loads. Some classic linear viscoelastic models were adopted to predict creep curves of the material. Nonlinear creep behavior was investigated by the time-stress equivalence principle. It is revealed that the main curves of equivalent creep compliance can be described by using linear model. |

| Keywords: | butyl rubber viscoelasticity creep time-stress equivalence |
