This study aims to contribute to the ongoing efforts to enhance the reliability and durability of wind turbine blades, a critical component in wind energy generation. Specifically, this research addresses the issue of tunneling cracking and severe damage that can occur in wind turbine blades due to cohesive failure of the trailing edge. To achieve this objective, the study employs a rigorous approach, utilizing a full three-dimensional (3D) modeling strategy with finite element analysis (FEA) to simulate the behavior of wind turbine blades. The effect of cohesive materials and layered simulation methods on the thermal residual stress and crack propagation is thoroughly investigated. In particular, the study assesses the influence of carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP) materials on the phenomenon under consideration. In addition, the study undertakes a comprehensive parametric analysis to identify the independent effects of material properties and numerical simulation on thermal residual stress. Moreover, the research explores the behavior of the cohesive zone model in terms of thermal residual stress and crack propagation. The findings of this study have significant implications for researchers and practitioners in the wind energy industry. The study's outcomes can aid in the development of improved materials and simulation techniques to mitigate thermal residual stress and prevent the occurrence of tunneling cracking and other types of damage in wind turbine blades. As such, this research contributes to the broader efforts to advance the reliability, efficiency, and sustainability of wind energy generation.
