Initiation mechanism of transverse cracks in wind turbine blade trailing edge [PDF]
Energy Engineering, 2020 Transverse crack often occurs in the trailing edge region of the blade when it is subjected to excessive fatigue load in edgewise. In this paper a refined model was established through local mesh refinement methods in order to investigate the initiation mechanism of crack and its extension in blade trailing edge. The material stress around the crack in
