Micro Abstract:
This contribution aims to clarify the need for considering non-proportionality in the fatigue analysis of adhesive joints of wind turbine rotor blades. The comparison covers three different blade configurations (Length: 20 m, 40 m and 80 m) in order to derive generalized conclusions by extracting a correlation between non-proportionality, radial position and blade size. The results further indicate which type of fatigue analysis has to be performed for reliable life estimations.
