1. A notch methodology to estimate fretting fatigue strength
The aim of this work is to propose a methodology to estimate the fatigue limit of cylindrical contacts under a partial slip regime. Taylor’s point stress method, usually applied to estimate fatigue limit for notched structures, was associated with the Modified Wöhler Curves to define the fretting crack initiation threshold methodology. Twenty-nine tests o

2. Estimativa do limite de fadiga sob condições de fretting considerando o método da distância crítica do ponto em uma abordagem por elementos finitos
The goal of this work is to evaluate the fatigue limit of components under fretting conditions through a methodology usually applicated to notched componentes. The proposed methodology is based on the application of multiaxial models proposed by Dang Van and Susmel and Lazzarin (Method of Wohler Curve Modified) in terms of the Theory of Critical Distance by

3. The application of a mesoscopic scale approach in fretting fatigue
This work concerns the application of a mesoscopic scale fatigue criterion to predict the initiation of cracks in components under fretting conditions. A verification of the analysis is carried out by considering available experimental data for fretting fatigue in a high strength Aluminium alloy commonly used in the aerospace industry. These experiments reve
