Pressured apparatuses (such as pressure vessels) are widely used in many fields as key equipment including chemical, petrochemical, mechanical, weaponry, aviation, aerospace, energy, material, food, metallurgical, pharmaceutical and construction industries, etc. Autofrettage technology is an effective measure to improve the safety and the load-bearing capability of pressured apparatuses. This book comprehensively and systematically studies autofrettage technology of pressured apparatuses to introduce many valued phenomena and relevant laws. New theories of autofrettage technology are established, and new autofrettage technologies are proposed in this book. Authors present a large number of formulas, figures and application examples to facilitate the understanding and application of the new theories and new technologies. This book is characterized by strict demonstration and close combination with practical application. It serves as a reference book for analysis and design of pressured apparatuses which are widely used in many industries, and provides learning and teaching materials for students, teachers and engineers.
