The objective of this work is to study the elastic stress distribution, deformation characteristic, and stress concentration factor (SCF) of a cylindrical vessel with lateral nozzle. Three full scale vessels under internal pressure with different geometric dimensions and lateral angle are investigated by both experimental and three-dimensional finite element methods under internal pressure. A detailed stress distribution and the SCFs of the model vessels are provided. The results indicate that the maximum stress of cylindrical vessels with a lateral nozzle occurs at the acute side of the cylinder-lateral intersection and drifts off the longitudinal section of the cylinder for about 20 deg. When the geometric parameters of the vessels are fixed, the SCF of the structure will increase with a decrease in the lateral angle .
