CHAPTER 13 Blade materials, testing methods and structural ...
scale blade testing including some results for blades tested to failure (Section 3) that leads to a classifi cation of common failure modes (Section 4). The material properties that control the development of the various failure modes are presented in Section 5. Section 6 describes experimental methods for determination of these properties.
