Investigation of the Effect of Wrinkle Features on Wind Turbine Blade Sub-structure Strength - ScienceDirect
Wrinkles are known to have a strong knock-down on the mechanical performance of structures made from composite materials. Here, static tensile tests were conducted to investigate the effect of wrinkle features on the strength of a wind turbine blade sub-structure, representative of a blade root feature. A pultruded tapered insert is embedded in each sub-structure and the wrinkle is in close vicinity to the termination of the tapered insert. Each of the tested sub-structures was then numerically modelled using finite element simulations....
