“…In addition, it deserves our attention that for blade fatigue, a short period of high loading cycles may determine the fatigue life. As a consequence, not only wind fluctuations, but also atmospheric and environmental phenomena, such as coastal storms, lightings and gusty winds which caused many downtimes to wind turbines should be considered in fatigue reliability design and evaluation [87,88].…”

“…The aerodynamic load is engendered by the lift and drag of the blade airfoil, which is calculated using (BEM) theory for each blade element. Using the ABAQUS software, the forces are thus calculated and applied homogeneously along the section of the blade 45 …”

“…The centrifugal force applied to the blade is caused by the rotation of the rotor at an angular velocity (ω). This force is calculated using the Equation ) 43,45

F_{c} = \frac{1}{2} m \times ω^{2} r

where ω, m, r are, respectively, the rotational velocity, the mass of the blade and the distance of the blade element from the center of rotation.…”

Summary In northern regions, wind turbines are affected by the formation of ice on the surface of their structures, which usually occurs on moving blades, resulting in a significant decrease in aerodynamic performance and then the output power tends to reduce. This research evaluates the mechanical behavior and damage of the proposed composite blade structure under icing conditions. A comparative evaluation was carried out considering three ice configurations and three blade positions. The results are then examined and analysed. During this study, the blade in service was subjected to three different critical loads. A numerical simulation is adopted using finite element method (FEM) with ABAQUS software to localize damage in the composite wind turbine blade. The method developed is based on the failure criteria of HASHIN to detect failure modes in large structures and to identify the most sensitive zones. Major damage appeared in the transition region and was the principal reason for the composite blade failure. Furthermore, greater strength and stiffness were found with Carbon (CC) fibers blade designs, whereas configuration 3 was found to be the best one, and the optimal blade position was when the ice structure was placed vertically.

The implementation of composite materials in industries like aerospace, automotive, civil, naval, etc., are emerging continuously because of its combined unique effects. The present article deals with a numerical simulation of the natural frequency effect on the different cantilever structure for various composite materials also estimates its structural response to aerodynamic forces using Fluid-Solid Interaction (FSI) in Ansys Workbench environment. This work is intended to analyze and learn the response of various real-time structural parameters like maximum deformation, maximum stress-induced location and modal parameters like modal frequency, mode shapes on different Cantilevered structures. Structures like wind turbines, airplane wings are critical in structural behavior, which are characteristically using the wind to produce power and lift respectively. The present article deals with an estimation of natural frequencies for the prediction of working lifespan and structural parameters variation throughout the cantilever structures to multi-purpose usage. The entire comparative part of this article is executed with an acceptable simulation of the displacement and principal stress for different composite materials such as Kevlar, Glass Fiber Reinforced Plastic (GFRP) and Carbon Fiber Reinforced Plastic (CFRP) by using FSI. Composites Beams are modeled in CATIA and discretized in the Ansys ACP 16.2 tool and Modal analysis of various crosssectional beams are reported, compared and discussed.
