Abstract

This work deals with mechanical properties of a rubber material that is used in modern tram wheels as a damping element. Nonlinear static response as well as strain softening and hysteresis are captured in the material model. The identification method of the model’s parameters is developed. The identification method relies on successive minimizations with respect to different sets of parameters. The identification of the parameters of the material model is based on the tensile and compressive experimental data. Shear data are used for validation.
