ObjectiveThe corrosion fatigue fracture of the wind turbine pitch bearing is a major failure mode, often leading to the blade detachment and shutdown. To this end, a finite element model of replacing the whole pitch bearing with a local one was proposed to investigate the structural fatigue remainin...
