Fatigue Analysis Summary

 

For each end point of each piping element, PIPESTRESS generates a fatigue analysis summary report, shown below, documenting the 12 conditions defined in the fatigue analysis legend.

 

For each point at which one of the conditions is reported, PIPESTRESS documents the usage factor calculation in report F-4.2.
