Abstract: The paper presents the results of experimental verification of analytic model of cyclic properties description. The subject of verification was the two-parameter model of Ramberg-Osgood (R-O). The research was carried out at two temperatures using the test pieces of high-chromium martensitic cast steel. The model was assessed by making a comparison of parameters of the hysteresis loop obtained from the calculations using the R-O model. Analysis of the tests and calculations results revealed their diversity depending on the temperature and level of strain covered in the research.
