The purpose of this study is to present a methodology which estimates the fatigue life of interference fit fastener and cold worked holes. This methodology is mainly based on the determination of local stress with finite-element model computations and on the use of a multiaxial fatigue model. This approach is compared with experimental results carried out on test specimens representative of narrow body civil aircraft components. Analysis of the results shows a highly satisfactory correlation between prediction by calculation and experimental data. Copyright © Elsevier Science Limited.
