Stress Analysis of Reinforced Nozzle-Cylindrical Shell Intersection Under Internal Pressure or Nozzle Radial Thermal Expansion

Abstract

Two normally intersecting cylinders under different internal pressures in each of the cylinders is solved analytically. The inclusion of nozzle fillet, insert plate and inner nozzle broadens the applicability of this analytical method in the design and analysis of pressurized cylinder-to-cylinder intersection. The current numerical solution scheme has been incorporated in the computer code NUTSHELL. Comparisons of NUTSHELL solutions and experimental or finite element results have also been presented.
