摘要
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. (C) 2010 Elsevier Ltd. All rights reserved.
