Abstract

Design of pressure vessels is covered by references such as the ASME Pressure Vessel Code and textbooks devoted to pressure vessel design. Detailed stress analysis, particularly in the area of discontinuities, is generally left to the design engineer. The type discontinuity addressed in this paper is the design of bolted flanges for a pressure vessel. Work for this project involves optimization of the hub contour using the ASME Pressure Vessel Code requirements as constraints. This paper summarizes the initial woik, development of the BEM (BE ASY) models and verification of the model to classical techniques such as a "Roark" [12]. This two- dimensional model will later be expanded to a full, three-dimension model; and, will also provide data for establishing allowable defect sizes, based upon inspection techniques and design life.
