Wind Turbine Blade
Created using ANSYS 13.0
Problem Specification
This tutorial is based on this M.Eng project report completed at Cornell University in 2011. In this exercise, we will examine the stresses and deformation of a wind turbine blade under a force load.
The blade is composed of an outer surface and an inner spar. The spar is 0.02 meters thick and the outer surface is of varying thickness. A table containing the material properties of the two parts is below. Structural steel will be used for both the blade and the spar.
