Determination of Vibration Borne Stress in a Pipeline Using Fluid Structure Interaction

Excessive vibration is one of the leading causes of high cycle fatigue in process piping. Conventional way to assess the severity of vibration is to measure the stress caused by vibration with strain gages. An alternative way is discussed in this paper. The basis of this alternative way was formed b...
