Numerical Analysis of Composite Wind Turbine Blade Considering Failure Behavior

Abstract:

The paper studies the failure of the 3-D complicated configuration composite turbine blade by applying failure criterion. This failure criterion considers three kinds of different failures. They are matrix tensile/compressive failure, fiber- matrix shear failure and fiber failure. By Using FEA software ABAQUS, the stiffness degradation and failure behavior of the turbine blade of composite structure were studied. The failure and stiffness degradation of the two analysis models were conducted by typical numerical examples as well.
