The Stress Analysis of Pressure Vessels and Pressure Vessel Components

The Stress Analysis of Pressure Vessels and Pressure Vessel Components, Volume 3 deals with the basic principles and concepts underlying stress analysis of pressure vessels and related components used in the nuclear energy industry. Among the components subjected to stress analysis are pressure vessel branches, pressure vessel ends, local attachments, and flanges. Smooth and mitered pipe bends, externally pressurized vessels, and creep effects in structures are also analyzed. This book is comprised of 11 chapters that explore the main problems of structural analysis related to the design of metal pressure vessels and components. After introducing the reader to the basic principles of stress analysis, it turns to nozzles in pressure vessels. The shakedown analysis of radial nozzles in spheres is described for pressure, thrust, moment, shear, and combined loading. The problem of pressure vessel ends is treated next, along with local loads applied to pressure vessel shells at nozzles and local attachments such as support points. An analysis of pressure vessels using a computer is also presented. The final chapter describes the analysis of ligament stresses in pressure vessels and includes a discussion on arrays of holes with reinforcement. This volume will be of value to nuclear and structural engineers as well as designers and research workers in the nuclear industry.
