Sažetak
Methods for the estimation of strain life fatigue parameters from monotonic properties are usually evaluated for a wide range of fatigue lives and materials. Authors propose estimation methods to be evaluated separately for low- and high-cycle fatigue regimes and for more subgroups of materials, with regard to their monotonic properties. To test the hypothesis, three methods (Uniform Material Law, Median Method and Roessle- Fatemi's Hardness Method) were evaluated using a test dataset of 32 differently heat-treated low- alloy 42CrMo4 steels. Results indicate that existing estimation methods should be re-evaluated to determine more precisely their applicability for different materials and fatigue regimes.
