An illustrative guide to the analysis needed to achieve a safe design in ASME Pressure Vessels, Boilers, and Nuclear Components

Stress in ASME Pressure Vessels, Boilers, and Nuclear Components offers a revised and updatededition of the text, Design of Plate and Shell Structures. This important resource offers engineers and students a text that covers the complexities involved in stress loads and design of plates and shell components in compliance with pressure vessel, boiler, and nuclear standards. The author covers the basic theories and includes a wealth of illustrative examples for the design of components that address the internal and external loads as well as other loads such as wind and dead loads.

The text keeps the various derivations relatively simple and the resulting equations are revised to a level so that they can be applied directly to real-world design problems. The many examples clearly show the level of analysis needed to achieve a safe design based on a given required degree of accuracy. Written to be both authoritative and accessible, this important updated book:

• Offers an increased focus on mechanical engineering and contains more specific and practical code-related guidelines
• Includes problems and solutions for course and professional training use
• Examines the basic aspects of relevant theories and gives examples for the design of components
• Contains various derivations that are kept relatively simple so that they can be applied directly to design problems

Written for professional mechanical engineers and students, this text offers a resource to the theories and applications that are needed to achieve an understanding of stress loads and design of plates and shell components in compliance with pressure vessel, boiler, and nuclear standards.

Membrane Theory of Shells of Revolution

1.1 Introduction

All thin cylindrical shells, spherical and ellipsoidal heads, and conical transition sections are generally analyzed and designed in accordance with the general membrane theory of shells of revolution. These components include those designed in accordance with the ASME pressure vessel code (Section VIII), boiler code (Section I), and nuclear code (Section III). Some adjustments are sometimes made to the calculated thicknesses when the ratio of radius to thickness is small or when other factors such as creep or plastic analysis enter into consideration. The effect of these factors is discussed in later chapters, whereas assumptions and derivation of the basic membrane equations needed to analyze shells of revolution due to various loading conditions are described here.

1.2 Basic Equations of Equilibrium

The membrane shell theory is used extensively in designing such structures as flat bottom tanks, pressure vessel components (Figure 1.1), and vessel heads. The membrane theory assumes that equilibrium in the shell is achieved by having the in‐plane membrane forces resist all applied loads without any bending moments. The theory gives accurate results as long as the applied loads are distributed over a large area of the shell such as pressure and wind loads. The membrane forces by themselves cannot resist local concentrated loads. Bending moment...
