Abstract

Highlight: 73 + 80 (fretting + plain) fatigue experiments used to validate fatigue criteria. The stress-based Brown-Miller method performs best overall. The Dang Van method suffers from high scatter of results. Methods based on normal and von Mises stress yield too nonconservative results. Abstract: The work published in this paper attempts to validate selected fatigue criteria on fretting fatigue laboratory experiments collected from the available literature. The local stress response was analyzed by 11 fatigue prediction criteria, which varied in the way of processing the stress or strain tensors, in the correction of the mean stress, or in involvement of the stress gradient correction. The criteria were selected on the basis of their availability in commercial fatigue solvers and on the basis of the ways in which they are implemented, so that the analysis of published results closely reflects engineering practice.
