摘要：

Crack growth in a shrink-fit assembly subjected to rotating bending was studied. Two finite element (FE) models and a numerical routine were implemented to evaluate the contribution of the fretting load and to compute the crack growth. Numerical results for the crack propagation were compared to each other and to experimental data from the literature. Good agreements were found for the stress intensity factor (SIF) computations and for the crack propagation life. A significant reduction in the fatigue crack propagation life, up to 50%, was found as compared to an equivalent pure bending case. (C) 2007 Elsevier Ltd. All rights reserved.
