Many structures operate at elevated temperatures where creep and rupture are a design consideration, such as refinery and chemical plant equipment, components in power-generation units, and engine parts. At higher temperatures the material tends to undergo gradual increase in dimensions with time, which could eventually lead to rupture. Thus, the design of such components must take into consideration the creep and rupture of the material. In this book, a brief introduction to the general principles of design at elevated temperatures is given with extensive references cited for further in-depth understanding of the subject. A key feature of the proposed book is the use of examples to illustrate the practical application of the design and analysis methods presented. This book is suitable for practicing design engineers in the power and process industries, particularly those in involved with pressure equipment, nuclear structures, petrochemical equipment, and their supervisors.
