Stress Intensity Factor Analysis of Nozzle Considering Pressure and Heat Transfer on Crack Face Jeong, Min-Jung; Kim, Yeong-Jin; Gang, Gi-Ju; Beom, Hyeon-Gyu; Pyo, Chang-Ryul;
In order to investigate the effect of nozzle on stress concentration in pressure vessels, three dimensional finite element analyses were performed. The results were compared with those for corresponding two dimensional axisymmetric finite element analyses. A three dimensional finite element model with a surface crack was also designed to evaluate the effect of internal pressure and heat transfer on crack face, and the resulting stress intensity factors from the finite element analyses were compared with those for ASME Sec. XI and Raju-Newman's stress intensity factor solution. As a result, the validity of currently available stress intensity factor solutions for a surface crack was reviewed in the presence of geometrical complexity, heat transfer and internal pressure.
