Development of a multiple-specimen, reversed-flexure fatigue tester and its application to the testing of titanium sheet

"Advancing technology constantly increases the demands on existing engineering materials. These demands are extremely severe for aerospace materials where the necessity for a higher strength-to-weight ratio is complicated by little understood environmental effects. A major consideration when designing structures is the fatigue resistance of available materials. The goals of this investigation were the development of a multiple-specimen fatigue tester and the evaluation of the fatigue properties of commercially pure titanium in a room-temperature air environment. The resulting fatigue tester is capable of simultaneously testing six sheet specimens in reversed bending at speeds up to 2000 cycles per minute. Fatigue properties of 0.035-in. thick commercially pure, grade Ti-75A titanium sheet were evaluated and results are presented in the form of an S-N curve including data for the rolling and transverse directions. These data were analyzed statistically and compared with the results of previous investigations of this type material."--Introduction.
