Wind turbine blades are subject to complex environmental and mechanical loading during their service time, including cyclic deformation, rain, sand and contaminants causing erosion, icing, high moisture and temperature variations, but also extraordinary events, such as. Wind turbine blades are subject to complex environmental and mechanical loading during their service time, including cyclic deformation, rain, sand and contaminants causing erosion, icing, high moisture and temperature variations, but also extraordinary events, such as. A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. In particular, the mechanisms of leading edge erosion, adhesive joint degradation, trailing edge failure, buckling and blade collapse phenomena are considered. Methods of. Damage to wind turbine blades can be induced by lightning, fatigue loads, accumulation of icing on the blade surfaces and the exposure of blades to airborne particulates, causing so-called leading edge erosion. For operators, understanding the most common blade issues and implementing effective prevention strategies is essential to ensure consistent energy. Wind turbine blades are constantly exposed to harsh weather, making them vulnerable to physical wear, fatigue, and environmental damage. Unlike enclosed mechanical systems, blades must endure a wide variety of external stressors, which increases their failure rate. Key reasons blade failures occur.
