BULLETIN 96-1964 STRESSES NEAR A CYLINDRICAL OUTLET IN A SPHERICAL VESSEL EFFECTS OF EXTERNAL LOADINGS ON LARGE OUTLETS IN A CYLINDRICAL PRESSURE VESSEL
The purpose of this report is threefold: (a) to derive a stress analysis of the sphere-cylinder structure that treats the two components with a minimum of overlap at their junction; (6) to present a computational procedure that employs only three geometrical parameters@ so as to facilitate the calculation of critical stresses over a wide range of sizes and proportions@ in other words@ a largescale parametric study@ and (c) to include one or more tables of numerical values that can be used for the simplified calculation of stresses at any point in the neighborhood of the sphere-cylinder junction. All results are based on an internal pressure of 1 psi and a mean sphere diameter of 1 inch; values for other pressures and sizes are obviously in direct proportion. This study was undertaken as part of a general investigation of the reinforcement of openings in pressure vessels by the Pressure Vessel Research Committee of the Welding Research Council. The intent was to obtain stress values for radial cylindrical outlets in spherical pressure vessels that could be compared with experimental results in the same field. If@ as a result of this comparison@ the theoretical data appear to be reasonably valid@ they can then be used as a basis for the estimation of stress conditions in openings of this type@ over the whole range of sizes and proportions currently employed in industry.
