The Comparison of Cyclic Properties of X5CrNi18-10 Steel in the Range of Low-Cycle Fatigue in Conditions of Stress and Strain Control

Abstract:

Service loading of constructional elements are caused by mass forces (dynamic loading) or displacement (kinematic loading). There are methods of estimation of cyclic properties of material based on stress or strain range control corresponding to the mentioned loading types. The paper includes an analysis of differences between diagrams determined in controlled stress and strain conditions as well as relations among: Wöhler curves (W), Manson-Coffin curves (M-C) and Ramberg-Osgood curves (R-O). Basing on the performed analysis there have been formulated conclusions that generally are on connecting loading character with conditions of determination of atigue curves.
