Progressive Failure Analysis for 5MW-Class Wind Turbine Composite Blades with Debonding Damage based on CZM Method
نویسندگان
چکیده
Composite wind turbine blades may experience interlaminar damage, including adhesive failure, cracking, and fracture from manufacturing or external fatigue load. Among these, the failure of joints is critical. Therefore, it important to identify mechanism in between spar cap–shear web trailing edge composite blades. We calculated toughness through Mode I, II, Mixed-mode tests for quantitative analysis joints. Then, select a modeling method realizing damage generated blade, was verified specimen level. A model constructed, considering contact conditions an NREL 5MW blade. Finally, based on cohesive zone used analyze progressive behavior debonding at according force applied

متن کاملTesting and Condition Monitoring of Composite Wind Turbine Blades
In a wind turbine system, blades are one of the most critical components. They capture energy from wind and convert it to a mechanical energy for electricity power generation. However, once the blades are defective, the power generation efficiency of the turbine will be significantly affected. In worse case when the blade is seriously damaged, the turbine will have to be shut down completely fo...
