Aug 13, 2015: When a bearing inside a wind turbine is subject to a load, its thickness is reduced by a very small amount due to elastic deformation, and the speed of sound is affected by the stress level in the material. Both these effects change the time of flight of an ultrasound wave through a bearing. A novel technique has been developed to predict when bearings inside wind turbines will fail which could make wind energy cheaper.
