The stabilized hysteresis loop was determined for the material of railway wheel, by the condition of steady amplitude of axial strain. The compressive test by laboratory and elevated temperature were also performed. The Chaboche material model and the nonlineaar kinematic material model was designed for this material. Theese material models were used in numerical simulations of rail wheel rolling on the rail. The stress strain responses, residual stresses and the different high cycle fatigue criterion were compared and the suitabiliy of used material models was discused.
