“…This criterion [36] was created with the interesting idea of extending the applicability of the general Gough-Pollard criterion to more complicated cases that also encompass the general plane stress state, including another normal stress component. The original Gough-Pollard formula combining the axial stress amplitude σ xa and the shear stress amplitude τ xy follows:…”

“…which was expected to better describe the response of the materials in their experiments. The general formulation of the KP criterion [36] is based on extending the original axial stress term to a formula, which also encompasses the second possible normal stress σ y :…”

“…There are three material parameters involved (a KP , b KP , and c KP ), the phase shift between both normal stresses δ yy and two stress parameters σ m,B and σ m,C , which are calculated from complicated formulas [36] composed of mean values and amplitudes of all involved stress channels. The two last addends in Equation ( 4) describing the effect of mean stresses are completely retrieved from the paper by Liu [37].…”

“…The two last addends in Equation ( 4) describing the effect of mean stresses are completely retrieved from the paper by Liu [37]. The lengthy definition of σ m,B and σ m,C is so complicated that the authors of [36] admitted in personal communication that an error was induced in the transcription of two from all parameters, and thus the correct formulation should be found in [37]. Two of the material parameters involved in Equation ( 4) are:…”

The paper presents a comparison of six recently introduced multiaxial fatigue strength estimation criteria to four methods, the large-scope validation of which has already been published. The results obtained for each newer method are analyzed and discussed. From the newer methods, only the criterion by Böhme reaches an estimation quality similar to the best performing criteria. The validation was performed on the FatLim data sets, but the primary focus of the paper is set to analyzing the validation on a smaller AMSD25 data set derived from it. The comparison shows that the application of AMSD25 for validation practice allows users to reduce the number of evaluated test cases, while generally preserving the worst cases showing the weaknesses of various estimation methods.

This paper describes the way in which a specialized validation set intended for quick validation of new multiaxial fatigue strength estimation models in the high‐cycle fatigue regime was prepared. The rules established for accepting various data sets into the complete FatLim database are briefly described. This final FatLim database contained 282 data items at the moment this paper was written. The paper describes how FatLim has been reduced to a smaller validation set, marked as AMSD25. The criteria used for accepting the data items for this small‐scale test set are based on evaluating the mean and the standard deviation of the fatigue index errors obtained for each data item on the basis of 18 different prediction criteria. The items that got into the AMSD25 validation set are described, and potential issues are noted. The comparison between the original FatLim validation set and the shortened AMSD25 data set is presented. It shows that the in‐phase load cases without any mean stress effect are generally well mastered by most criteria, and they can be excluded as insignificant from any such analysis. However, the mean stress effect is generally poorly incorporated. Future multiaxial fatigue strength criteria should focus on load cases including mean stresses.
