Short summary
Wrinkles are production defects of wind turbine blades characterized by fibre waviness through the laminate thickness. Such defects are pointed to as one of the primary sources of premature failure of the blade, which impacts the structure's structural reliability. This work shows a methodology to evaluate the impact of wrinkles on wind turbine blades featuring preliminary results, which present the detrimental effect of small wrinkles on the structural response of the blade.
