The real material structure taken from a railway wheel was loaded on a test equipment to find its stress-strain characteristic. The determined material variables were verified in the quoted computation. This paper presents results from the analysis with cyclic loading of two wheels with different diameters which are in mutual contact. The target of this research is to simulate by computational methods the low-cycle fatigue approved by metallurgical analyses.
