Abstract

A thermodynamically based continuum damage mechanics (CDM) approach is employed as a propitious method for analyzing fretting crack nucleation. Intense fretting stress gradients in the contact region are examined and believed to be highly influential in the crack nucleation process. A methodology is proposed that allows for identification of an averaging zone as a function of the contact and loading parameters. The results predicted by this approach are verified by comparing the CDM crack nucleation predictions with the published experimental results on crack nucleation lives. Good agreement is observed between the predictions and the experiments. © 2011 Elsevier Ltd. All rights reserved.
