Fatigue Failure of a Redundant Structure

Source

Multiple-load-path redundant structures have been utilized in “fail-safe” design applications for a long time without a thorough investigation into the statistical nature of their failure. Experiments conducted at the Institute for the Study of Fatigue and Reliability, of Columbia University, on a model ten-member redundant structure subjected to constant-amplitude loads have been analyzed, and the statistical distribution of consecutive failures was determined. The experimental results are compared with various theoretical computations which were found to be conservative.
