✦ Synopsis

This paper presents a comprehensive overview of the main currently published fatigue prediction models for estimating the multiaxial fatigue limit. The set of analyzed criteria comprises 17 different methods, which are tested on a series of 407 experiments. The methods are briefly described and the overall tendencies of their prediction capabilities are commented on, including some properties common to certain groups of criteria. The set of experiments refers to the publicly available FatLim database. The computation results were achieved using the PragTic freeware fatigue solver. The Papuga PCr method is the best solution at present. Some possible ways of further improving the methods are proposed here.

The classical strength hypotheses are not applicable for the calculation of the fatigue limit under multiaxial loading with changing directions of the principal stresses. Hitherto, two groups of concepts have been proposed, the critical plane approach and the integral approach. In the present paper

The goal of the present paper is to propose a criterion to predict the fatigue strength of hard metals under conditions of multiaxial, non-proportional loadings. It is very simple to compute, but still provides very good results for a wide range of in-phase and out-of-phase cycling loads.
