Fatigue Testing with Periodic Heating - An Investigation of Some Methods of Acceleration.
Abstract
Tests were conducted on aluminium alloy notched and riveted joint specimens under flight-by-flight loading sequences to examine the effects of varying the number of applications of heat and the maximum temperature. The effect of these parameters on fatigue life, and the underlying mechanisms are discussed. It is shown that changes in the number of applications of heat and in the maximum temperature cause appreciable changes in performance. An observation of general significance was that fatigue lives were affected by the inclusion of periods of load dwell in tests at a constant temperature of 40 C. A description is given of the multi-channel testing facility used for this work. (Author)
