Experimental and analytical study of cracks under biaxial fatigue [PDF]
Most mechanical components experience multi-axial cyclic loading conditions during service. Experimental analysis of fatigue cracks under such conditions is not easy and most works tend to focus more on the simpler but less realistic case of uni-axial ...

A Full-Scale Tidal Blade Fatigue Test using the FastBlade Facility
Fatigue testing of tidal turbine blades requires the application of cyclic loads without the ability to match the natural frequency of the blade due to their high stiffness and the associated thermal issues of testing composite materials at those frequencies (i.e., 18–20 Hz).

High Specification Offshore Blades. Work Package: 1C – Blade Materials. [PDF]
Blades are regarded as the only component unique to wind turbine blades. They represent only 10 – 15% of the total system cost so the perception is that a reduction in the cost of energy through blade cost improvements is constrained.
