DETERMINATION OF STRESSES AT NON-RADIAL OPENINGS IN SPHERICAL PRESSURE VESSELS.

Abstract

An attempt was made to simulate experimentally the theoretical case of an oblique hole in a pressurized spherical vessel. For the case of an opening of diameter ratio 0.129 and at 45 degrees to the radial direction, seven different closure schemes were tried. These are listed as WS-16B1, WS-16B1 A to F, inclusive. Radically different stresses were obtained for each closure scheme, indicating a very sensitive dependence of stress on closure conditions. For 0 degree section (i.e., the section in which the acute angle between the opening and the vessel is at the inner surface) the maximum stress varied from 2.55S to 4.81S, S being the nominal stress in the spherical vessel. For the 180 degree section, the maximum stress variation was from 3.06 to 6.75S. (Author)
