Fatigue analysis in AutoPIPE Vessel is used to evaluate the cumulative damage caused by cyclic loading during the operating life of pressure vessels and heat exchangers. It is especially relevant when equipment is subjected to repeated pressure, temperature, or mechanical load variations, which may lead to crack initiation and propagation even when stresses are below allowable limits for static design.
This capability is primarily intended to demonstrate code compliance and long‑term integrity for cyclic service conditions.
The fatigue checks are executed only when the selected code and model configuration support fatigue evaluation.
