Question

Give practical examples of high cycle fatigue failure.​

Answer 1

An example of fatigue failure was the airline crashes of the De Havilland Comets in 1954. Three of these passenger jets broke up mid-air and crashed within a single year. Sharp corners around the plane's window openings were found to have acted as stress concentrators which initiated cracks.
