ENGINEERING METHOD OF EVALUATING THE STRESS STATE OF ELLIPTICAL ENDS HAVING SET-ON NOZZLES

摘要

An engineering procedure is proposed for assessment of the stress state of elliptical bottoms with set-on nozzles as a function of their size. Diagrams and approximating equations to define stress-enlargement ratios, which are used to calculate brittle-fracture resistance and evaluate the cyclical strength of pressure vessels with nozzles are presented on the basis of alternative investigations.
