High Cycle Random Fatigue Testing

Abstract

Report discusses conceptual designs of automatic digitally controlled vibration fatigue test facilities for inducing high cycle random flexural fatigue of coupon specimens; recommends a facility for use at AFFDL; presents block diagrams and charts of major system components and subsystems. Report also describes random flexural fatigue tests conducted on aluminum and titanium riveted cantilever beam specimens with zero mean stress; presents data for 2024- T81 bare aluminum alloy at 75 degree F and 250 degree F, and for 6Al-4V annealed titanium alloy at 75 degree F and 600 degree F, for the range of ten to the 6th power through ten to the 9th power cycles to failure.
