Fluid Codes Confidential 1 Nozzle -Shell Junction Study • By using finite element analysis the stress concentration region of the Nozzle -Shell junction of a horizontal pressure vessel was determined and the reason was analyzed. • Sub-modeling Technique in ANSYS was used for the study to accurately predict the stress concentration • The result reveals high stress concentration is developed at this location due to abrupt change in the geometry and the consequent change in stress flow. The maximum stress is less than the yield stress of material. National Petroleum Construction Company (NPCC)© Copyright 2016. Fluid Codes FZ LLE.
