A method for estimating an energy loss of a high polymer material is disclosed. A model of the molecular structure of the high polymer material is defined. This model includes particle models and joining chains. Potentials are defined on the particle models. A high polymer material model in which the molecular structure models are arranged at cells is defined. A structure relaxation calculation is made. Thereafter, by applying a cyclic deformation to the high polymer material model, the stress and strain are computed, and the energy loss is computed therefrom. The deformation calculation is made only when the cycle of the cyclic deformation is not equal to the oscillation cycle determined by the characteristic frequency of the potential. |
