FEPROC Blade Model Verification - 3D Shell and Beam Model

The verification of a finite element model implementation of the DTU10MW wind turbine blade as a 3D shell and beam model is summarized. The in-house ANSYS Parametric Design Language toolbox FEPROC (Finite Element ProCedures) and BECAS (Beam Cross Section Analysis Software) were used to create the models. The FUSED-Wind blade parametrization together with  PGL (Parametric Geometry Library) were used for the blade planform and layup definition. The shell model was benchmarked with a solid model implemented in MSC Patran/Marc. While the modal and linear static responses agreed well, a discrepancy was found in the linear buckling response. The discrepancy was explained with the help of an analytical plate model. The beam model was benchmarked with the in-house anisotropic beam implementation ABeam, HAWC2 and BeamDyn showing good agreement. The dataset of the 3D shell and beam model is available at http://doi.org/10.5281/zenodo.1494044.
