Crack Growth Testing

Abstract

Test specimens of TI-6-2-4-2 were tested in an effort to determine the basic properties of the material. The main property investigated was the crack growth rate, da/dn, relative to the size of the crack, a, over the fatigue life of the specimen. Yield zones at crack tips were also investigated on tills material. Specimens of Beta2lS/SCS6, a titanium matrix composite, were also fatigue tested resulting in plots of crack growth rate, da/dn, against the stress concentration factor K. Effort was also devoted to the development and installation of a new data system.
