Numerical and experimental failure analysis of wind turbine blade

The aim of this study was to conduct a root cause failure investigation on the failed M30 × 530 mm stud utilized for connecting wind turbine blades to the hub casting.
Wind turbines: Dealing with blade root faults

Increasingly, many types of turbines are exhibiting blade failures, especially new designs, which might not have had as long a prototype testing stage as the industry was used to.
Analysis and Research on the Cause of Wind Turbine Blade Bolt

In 2019, inspection personnel of a wind farm went to the tower and found that a total of 6 bolts of blades in the hub of a wind turbine had broken and failed.
