Plant component case-study: header tubeplate ligament

Failure mechanism:Creep-fatigue, large thermal transients and over heating caused by tube restrictions

Stress state:Large thermal stress gradient due to temperature differences between tubes joint by the ligament. Potentially complex stress state and temperature history.
