摘要
A detailed study for the stresses around internally pressurized cylindrical vessel-cylindrical nozzle junctures is carried out using the finite element method. Based on thin shell theory, two simplified expressions (functions of the vessel-nozzle geometrical ratios) of stress concentration factor (SCF) are obtained: one for the main vessel and the other for the nozzle, respectively. The analysis was also used to study the location of maximum stresses at the juncture as well as provide a more accurate presentation of design charts than the rho-SCF plots. Verification is made using some established models available in the literature.
