Finite Element Model to Predict the Impact of Wrinkles on Wind Turbine Blades

Abstract: Among the manufacturing defects of wind turbine blades, wrinkles are critical to the blade performance, affecting the structural integrity. Therefore, this paper introduces three-dimensional numerical models of laminates representative of a wind turbine blade with artificial wrinkles. The models are verified against static tension-compression experimental tests of laminates embedded with two types of wrinkles. The results show a good correlation between numerical prediction and experimentally obtained stiffnes… Show more

“…The effect of defects in composite wind turbine blades has also been investigated by Nelson et al [ 31 ]. The influence of wrinkles on stiffness behavior has been analyzed numerically and experimentally by Mendonca et al [ 32 ], Bender et al [ 33 ], and others. Infrared thermography is a promising method for subsurface defect detection whose effectiveness has been proven in aerospace structures.…”
