Applicability of Axisymmetric Geometry Analytic Methods to Nozzles in Cylindrical Shells with Internal Pressure Loading

摘要

The work described in this report was undertaken in the hopes that stresses at nozzles in cylinders could be obtained with adequate accuracy using axisymmetric geometry methods for some small but useful range of d/D or d/D sqrt D/T. Methods investigated were equivalent sphere diameter; flat plate model; and sphere/plate model. Eringen's theory gives a reasonable estimate of the maximum measured stress in the test models.
