Fan blade roots of jet engines are operating under fretting sollicitations. This results in two types of damage: (i) initiation and crack propagation, and (ii) wear of contact surfaces. OBJECTIVE: A semi-analytical method has been developed in order to solve the industrial problem. This method is fast-computing and able to deal with elastic-plastic coated contacts and / or heterogeneous, and has bee developed from existing items and innovative analytical and numerical solutions. METHOD: The structure is simplified by assuming two semi-infinite elastic solid in contact, and analytical solutions for: + Contributions of elementary normal and tangential loads constant over a rectangular area + Contributions of elementary plastic strains const...
