Abstract:

The origins of residual stress and changes during fatigue are discussed. A new mechanism for fading is proposed. Practical destructive and non-destructive methods for measuring this stress are critically reviewed. Each technique has major problems requiring further study, but acoustic, magnetic and x-ray methods are all poised for more widespread use. Author
