“…Other studies [7,8] prove that the structural collapse of a WTB is the consequence of the combination of various failure modes: (1) spar cap buckling, (2) separation of the first layer, (3) bulge in the center of the cut, (4) detachment of the adhesive at the trailing edge, (5) matrix cracking, (6) the influence of the blade's weight, (7) manufacturing imperfections effects, and (8) the Brazier effect, mainly local buckling on the suction side of the airfoil (spar cap). Therefore, it is necessary to investigate the structural performance to predict the deformation and, in turn, the deviation of the WTB tip due to extreme deflections [9].…”
