Abstract
The investigation was a continuation of previous work involving the measurement of strains in the vicinity of forged rings of the type used to connect cylindrical ducts to large spherical shells. On two such rings of different shape strains were measured for the following loading conditions: internal hydraulic pressure in the vessel; axial loads applied to the nozzles; bending moments applied to the nozzles. Results for these two designs of ring, and two designs previously reported, have been compared.
An approximate method of assessing elastic stresses (in such rings) due to the effect of axial loads and bending moments has been found reasonably reliable as a design method.
A method previously found to give reliable predictions for the effect of internal pressure gave, for the two specimens considered here, lower estimates of maximum stress than the experimental maxima.
