Crack Growth Testing

reportActive / Technical Report | Accession Number: ADA361403 | Open PDF

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, dadn, 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 Beta2lSSCS6, a titanium matrix composite, were also fatigue tested resulting in plots of crack growth rate, dadn, against the stress concentration factor K. Effort was also devoted to the development and installation of a new data system.
