Summary:Abstract Adhesive bonding is widely distributed in wind turbine blades, and the fatigue performance analysis of the bonded layer is critical to investigate the safety and reliability of the whole structure. Various uncertainties influence the fatigue performance of adhesive bonding, originating from material, load, etc. A method for simulating fatigue that considers multiple uncertainties has been proposed in this paper based on the Cohesive Zone Model (CZM) and stochastic finite element theory. The study can provide reliable results for fatigue performance investigation of adhesive bonding in wind turbine blades.
