In the standard method, fatigue tests were performed with the use of many specimens, and in the simplified method, the results were defined in an incremental step test using one specimen. Test results were analysed taking into account the influence of loading form on the course of a stabilization process with defined material data. The analysis of the stabilization process in diversified conditions of loading was performed by comparison of the stress amplitude CTa and strain amplitude Eap for the same levels of total strain amplitude Eac• Basing on the tests, one could state that both methods of defining the cyclic properties lead to qualitatively and quantitatively convergent results. The results exhibit qualitative similarity as far as the character of courses of changes determined in different periods of life of n' and K' parameters of the cyclic strain chart is concerned, and quantitative similarity of the values of determined parameters.}, type={Article}, title={Comparative analysis of cyclic properties of 30 HGSA steel under constant - amplitude and incremental step loading}, URL={http://journals.pan.pl/Content/124962/PDF-MASTER/7_MECHANICAL53_2006_2_Mrozinski_Comparative.pdf}, keywords={low - cycle properties, fatigue life}, }
