Abstract :
In this paper a structural health monitoring technique considering the effect of wind on structural stability on laminated composite wind turbine has been investigated. Based on fluid structure interaction method and Hashin failure criteria, condition monitoring of wind turbine blades under sudden change of wind speed is investigated. The embedded fiber optic sensors are considered to detect the change in strain due to wind forces on the blades.
