Vibration-Based Damage Identification in Wind Turbine Blades

Due to the existing trend of placing wind turbines in impassable terrain, for example, offshore, these structures constitute prime candidates for being subjectedto structural health monitoring (SHM). The wind turbine blades have in particularbeen paid research attention [1] as these compose one of the most commonand critical components to fail in the turbines [2]. The standard structural integrityassessment of blades is based on visual inspection, which requires the turbinein question to be stopped while inspections are conducted. This procedure isextremely costly and tedious, hence emphasizing the benefits of developing andintegrating a reliable, remote monitoring method for detecting, localizing, and assessingpotential structural deterioration
