1 American Institute of Aeronautics and Astronautics Predicting Fatigue Life of Composite Wind Turbine Blades Using Constituent-Level Physics and Realistic Aerodynamic Loads Faisal Hasan Bhuiyan1, Dimitri J. In this paper, we present a comprehensive physics-based methodology for predicting fatigue life of a realistic composite wind turbine blade, working under realistic aerodynamic loads generated using a CFD model. Such empirical relationship based models are not well-suited to predict fatigue in a composite structure as large as a wind turbine blade, with the associated variability in loading and operating temperature. Modeling Approach Three separate modeling efforts were required in our approach to investigating the fatigue life of a wind turbine blade: a realistic finite element (FE) structural model of the wind turbine blade, a computational fluid dynamics (CFD) model to compute realistic aerodynamic loads on the blade, and a physics-based fatigue model for predicting fatigue life of the composite blade.

# Structural-Response Analysis, Fatigue-Life Prediction, and Material Selection for 1 MW Horizontal-Axis Wind-Turbine Blades. The problem of mechanical design, performance prediction (e.g., *flap-wise*/*edge-wise* bending stiffness, fatigue-controlled life, the extent of bending-to-torsion coupling), and material selection for a prototypical 1 MW horizontal-axis wind turbine (HAWT) blade is investigated using various computer-aided engineering tools. For example, a computer program was developed which can automatically generate both a geometrical model and a full finite-element input deck for a given single HAWT-blade with a given airfoil shape, size, and the type and position of the interior load-bearing longitudinal beam/shear-webs. In addition, composite-material laminate lay-up can be specified and varied in order to obtain a best combination of the blade aerodynamic efficiency and longevity. A simple procedure for HAWT-blade material selection is also developed which attempts to identify the optimal material candidates for a given set of functional requirements, longevity and low weight.

Rens Director: José Antonio Bea Cascarosa Doctoral Degree in Mechanical Engineering September 12, 2022 Group of Structural and Continuous Mechanics Probabilistic fatigue life analysis of wind turbine blade composite structures Preface This thesis was prepared in the Department of Mechanical Engineering of the Technical University of Zaragoza, in fulfillment of the requirements for acquiring a PhD degree. This thesis provides a review of the current state of the art of deterministic methods used to analyze the fatigue life of a wind turbine blade subject to fatigue loading, followed by a step-by-step explanation of probabilistic fatigue methods implementation using a finite element based structural model to increase the quality and reliability of the analysis input.

Assessment of the Influence of Erosion Wear on the Design Parameters and Useful Life of the C4-70 Family Centrifugal Fan. A method based on the wind speed spectrum and stress response at each wind speed is proposed to calculate the response spectrum of the dangerous part of the blade. Based on the generalized stress–life curve of the blade material, the fatigue damage accumulation model of the blade under random load is used to calculate the total fatigue damage of the blade and predict the fatigue life. In summary, in past research, the key to predicting the fatigue life is to calculate the fatigue damage of the blade, so choosing a suitable method to solve the fatigue damage of the blade is the key to estimating the life of the blade and the premise of calculating the fatigue damage of the blade is to obtain the blade response and then obtain the stress spectrum.
