Abstract

The present study presents a finite element analysis method with a shell element suitable for transverse as well as in-plane bending deformations to investigate the static and dynamic response of a horizontal axis wind turbine blade. It permits the modeling and analysis of blades with a good balance between accuracy and computational efficiency. This threedimensional approach is capable of accounting for the coupling between rigid-body rotation and large flexible deformations. In addition to the deformation response of the blade, it provides the stress and strain fields in the spar and the skin necessary for failure prediction.
