As wind turbine blades exceed 60 meters in length, the structural challenges and risks of failure increase significantly. Very large blades often fail due to a combination of fatigue and extreme loads, which are linked to specific local blade response phenomena such as out-of-plane panel bending and Cross Section Shear Distortion (CSSD). These issues highlight the critical need to address structural failures during the design and testing phases. Notably, full-scale fatigue tests often fail to replicate the most extreme local blade responses, as they do not adequately simulate the combined effects of edgewise and flapwise deflection, along with the torsional forces experienced by the blade during operation.
