STRESSES IN REINFORCED NOZZLE-CYLINDER ATTACHMENTS UNDER INTERNAL PRESSURE LOADING ANALYZED BY THE FINITE-ELEMENT METHOD A PARAMETER STUDY

摘要

A parameter study was conducted on stresses in reinforced nozzle-to-cylinder attachments under internal pressure loading as analyzed by the finite-element method. Twenty-five models with branch-to-run diameter ratios 0.08 < d/D < 0.50 and run diameter-to-thickness ratios 10 < D/T < 100 were investigated. A three-dimensional finite-element program, CORTES-SA, which was developed at the University of California at Berkeley specifically for analyzing tee-joint configurations, was used in the study.
