Kursusindhold
This course gives you an introduction to the materials used in wind
turbines and the loads they are subjected to. Simplify the wind
turbine to 4 connected cantilever beams (the tower and the three
blades), and the load and required material properties are
addressed. The procedure of extracting the material properties and
lifetime from experimental measurements is addressed. Focusing on
the composite material used in the wind turbine blades, the ability
to tailor, predict, and measure the mechanical properties of
composites is addressed. The course will be given as a combination
of online lectures, quizzes, demonstration videos, Python Jupyter
notebooks, and assignments used as a part of the final grading
