For these reasons, the implementation of a fatigue monitoring system can be an important advantage for the management of wind farms, providing the following outputs: (i) estimation of the evolution of real fatigue condition; (ii) since the real condition of fatigue damage is known, these results could be an essential element for a decision about extending the lifespan of the structure and the possibility of repowering or overpowering; and (iii) the results of the instrumented wind turbines can be extrapolated to other wind turbines of the same wind farm. In general, two distinct approaches in fatigue analysis can be followed [4]: (a) use the cumulative fatigue damage to predict fatigue life, assuming that a failure occurs after a number of loading cycles at a particular tension/stress range; and (b) examine the fracture behavior of mechanical elements under dynamic loads and consider that a failure occurs if the remaining strength of the component is insufficient because of cracks that have grown to a critical length.

However, due to the low accuracy level of current multiaxial macroscopic fatigue failure criteria and damage accumulation theories for predicting the fatigue-life of composite materials under multiaxial and variable cycle load conditions, the proposed probabilistic fatigue-life model seems unsuitable for wind turbine blades. Ustedes son y seguirán siendo un motivo para s[...]r breaks and the progressive appearance of new breakages both in different fibers (isolated) and along individual fibers (i.e., fragmentation) during the fatigue life 10 3 RESULTS AND DISCUSSIONS Figure 8: Comparison between the damage progression in regions close and far to the scrim fiber for different load levels: (a) and (b) σx,max = 320MPa; (c) and (d) σx,max = 340MPa. is presented.
