The first order shear deformation theory (FSDT) together with Hamilton’s principle approaches are detailed for eventual calculation of natural frequencies, thus, the approach evaluates the natural frequencies based on FE using Ansys Mechanical and Ansys composite PrePost (ACP) based on the FSDT method. A composite plate is assessed with and without artificial delamination to interpret dynamic performances about composite laminates of the blade structure. Consequently, a set of analysis studies has been carried on fiber’s orientation, laminates number, boundary conditions (BC), delamination area and their orientation. The most relevant findings from this research paper can be evaluated as those natural frequencies are decreased due to delamination progression of 7% at high vibration mode level; therefore, it reduces the robustness of the blade structure. In addition, the influence of BC is discussed regarding blade structure. As alternative solutions for revealing rigidity.

Composite materials are used in many wind structures such as renewable wind energy conversion systems because of their high-performance ratio (density/rigidity) compared to other materials. In this paper, the mechanical behavior of composite materials has been studied using a finite element (FE) to improve the mechanical strength and stability of a HAWTB. A nonlinear finite element model (FEM) is developed under FE in ACP software to simulate the mechanical behavior of the blade manufactured with composite material subjected to quasi-static wind loads.
In this study, the effects of three parameters are discussed: fiber materials, fiber orientation and ply thickness. The results showed a good agreement between our model and the experimental data with an error less than 1.56%.
The results of the finite element analysis (FEA) showed that the fiber's orientation, laminate thickness, and materials properties contribute highly to the mechanical robustness and stiffness of the blade.

The high demand of low cost wind energy needs to design large scale HAWTB with reduced weight, which poses a great challenge to their durability. Composite materials are being employed in many wind structures such as wind energy applications. In fact, external wind loads can cause damage mechanisms and large-deflection bending leading to test the ability of long composite WT blades. The paper is a comprehensive research on structural integrity of HAWTB by testing the structural part section cutted from the blade. The 3D complex geometry part represents the critical and structural part and it supports the main local failures initiation and progressive. The present part has been used for several analysis to investigate the coupled stiffness-strength and durability performance, using ANSYS, at extreme load conditions. The most advanced results obtained from nonlinear FEA of composite structural part concern the effect of fiber material on flap-wise displacement compared to Glass fibers.

The high demand of low cost wind energy needs to design large scale HAWTB with reduced weight, which poses a great challenge to their durability. Composite materials are being employed in many wind structures such as wind energy applications. In fact, external wind loads can cause damage mechanisms and large-deflection bending leading to test the ability of long composite WT blades. The paper is a comprehensive research on structural integrity of HAWTB by testing the structural part section cutted from the blade. The 3D complex geometry part represents the critical and structural part and it supports the main local failures initiation and progressive. The present part has been used for several analysis to investigate the coupled stiffness-strength and durability performance, using ANSYS, at extreme load conditions. The most advanced results obtained from nonlinear FEA of composite structural part concern the effect of fiber material on flap-wise displacement compared to Glass fibers.
