“…Rivera et al [23] reported progressive damage analysis of composite thin-walled beam (TWB) under reversed fatigue loading, showing that even though the initial failure first occurred in specific layers, the overall functionality of the structure had not significantly deteriorated over a long period of cyclic loading. Caous et al [24] compared fatigue lives of composite wind turbine blade by using normative approach (i.e. linear Miner rule) and progressive damage model.…”

“…Authors apply inertial and aerodynamic loads to sections separately through elements which allow an interpolation according to a user law. A second example of such an approach was provided by the TENSYL company (Caous and Valette, 2014) and is detailed in section ‘Comparison with other methods’. In this approach, the force and moment resultants are distributed between four nodes of each section, assuming simplified phenomenological laws.…”

“…This second method has been validated by the certification body DNV-GL to apply loads to a shell FEM of a wind turbine blade as part of a blade assessment, whereas the first method, using a rigid element, was not recommended (Caous and Valette, 2014). However, the first method is kept for comparison because it recurs in the literature.…”

It is common to dissociate load computation from structural analysis when carrying out a numerical assessment of a wind turbine blade. Loads are usually computed using a multiphysics and multibody beam finite element model of the whole turbine, whereas detailed structural analysis is managed using shell finite element models. This raises the issue of the application of the loads extracted from the beam finite element model at one node for each section and transposed into the shell finite element model. After presenting the methods found in the literature, a new method is proposed. This takes into account the physical consistency of loads: aerodynamic loads are applied as pressure on the blade surface, and inertial loads are applied as body loads. Corrections imposed by pressure and body load computation in order to match loads from the beam finite element model are proposed and a comparison with two other methods is discussed.

“…Caous proposed a progressive damage model by the ply scale to overcome the limitations of fatigue design optimization on wind turbine blades. The new model was also compared with the normative approach for the fatigue assessment and demonstrated its advantage in providing useful information to understand damage propagation [168].…”

With the depletion of fossil energy, offshore wind power has become an irreplaceable energy source for most countries in the world. In recent years, offshore wind power generation has presented the gradual development trend of larger capacity, taller towers, and longer blades. The more flexible towers and blades have led to the structural operational safety of the offshore wind turbine (OWT) receiving increasing worldwide attention. From this perspective, health monitoring systems and operational safety evaluation techniques of the offshore wind turbine structure, including the monitoring system category, data acquisition and transmission, feature information extraction and identification, safety evaluation and reliability analysis, and the intelligent operation and maintenance, were systematically investigated and summarized in this paper. Furthermore, a review of the current status, advantages, disadvantages, and the future development trend of existing systems and techniques was also carried out. Particularly, the offshore wind power industry will continue to develop into deep ocean areas in the next 30 years in China. Practical and reliable health monitoring systems and safety evaluation techniques are increasingly critical for offshore wind farms. Simultaneously, they have great significance for strengthening operation management, making efficient decisions, and reducing failure risks, and are also the key link in ensuring safe energy compositions and achieving energy development targets in China. The aims of this article are to inform more scholars and experts about the status of the health monitoring and safety evaluation of the offshore wind turbine structure, and to contribute toward improving the efficiency of the corresponding systems and techniques.
