In some cases this causes in sig ificant veraging of r sults of evaluations and possibly erroneous conclusions on estimation meth ds accuracy. A comprehensive evaluation of three selected, estimation methods was performed using establish d methodolo y on an xtensive number of detailed fatigue datasets on unalloyed, low-allo and high alloy steels. Results provide detailed insight on the accuracy of the selected estimation methods and their applicabilit for the estimation of fatigue parameters of various materials divided to low and high strength subgroups and for low- and high-cycle fatigue regimes. © 2020 The Authors.

In some cases this causes in significant averaging of results of evaluations and possibly erroneous conclusions on estimation methods accuracy.

Introduction Experimental characterization of materials behavior and the determination of their parameters, involves several challenges and problems such as variability in material behavior and response to various loading types that make it difficult to choose testing regimes, the appropriate number of test specimens, and complexity of test preparations. 1.
