Parametric study of the effect of wrinkle features on the strength of a tapered wind turbine blade sub-structure

Abstract: Parametric study of the effect of wrinkle features on the strength of a tapered wind turbine blade sub-structure. Composite Structures, 218, 120-129. AbstractOut of plane wrinkle defects are a major cause of strength reduction in structural composites. Therefore, this paper presents the numerical modelling of a wind turbine blade sub-structure with a tapered beam and a wrinkle. The model is validated against preliminary static tensile tests of a sub-structure without a wrinkle. There is a very good correlation… Show more

“…These two different shapes were used to achieve wrinkles with varying maximum wrinkle angles. The resulting wrinkles were characterised in the same manner as described in [24], which means that the location, depth of effect, wash out degree, length, and height were defined for each wrinkle. These features are illustrated in Fig.…”
