This paper deals with the analysis of the impact system, Which is composed of the ball and plane of high polymer materiales. An impact model considering both duration of impact and energy loss was proposed in a previaus paper. The impact system is modeled by both a nonlinear spring and a nonlinear dashopot using Hertz's contact theory. This model is applied to the impact system of high polymer materials. The validity of the model is shown from comparison between experiment and simulation without yielding of the materials. The experiment shows that characteristics of the impact change due to yielding of the material. An impact model in considering of yielding of the material is proposed. It is shown that the model can explain characteristics of the impact in the experiment.
