ABSTRACT:
Wind turbine systems, monitoring systems, and processes for measuring stress in a wind turbine blade generally includes embedding and or disposing optical glass fibers on a surface of the wind turbine blade and monitoring light transmission through the optical glass fiber. A reduction or loss of transmission indicates that the tensile strength of the optical glass fiber has been exceeded, which directly correlates to the level of stress exposed to the wind turbine blade.
