Flow-Induced Vibration Handbook for Nuclear and Process Equipment
12. Assessment of Fretting-Wear Damage in Nuclear and Process Equipment
Download citation file:
Generally, the problems caused by excessive vibration are fatigue cracks and fretting-wear damage. This chapter treats the problem of fretting-wear damage between a vibrating structure and its supports. Typical components of concern are piping systems and pipe supports, multi-span heat exchanger tubes and tube supports, and nuclear fuel bundles and fuel channels. Fatigue problems, on the other hand, can be analysed using classical methods that are readily available in the literature.
