Thermal Stress Analyses deals with both elastic and plastic thermal stresses produced from large variations in temperature and thermal expansion in materials whose properties are time-independent. This book is composed of eight chapters. The opening chapter illustrates the general three-dimensional thermoelastic problem, which requires the determination of stress, strains and displacements, when the body forces and boundary conditions are known while the next chapter demonstrate a simpler, two-dimensional formulation involving plane strain and plane stress. The succeeding five chapters describe thermal stresses in various structures, including in thin plates, beams, circular cylinders, and shells. The closing chapters consider the mechanism of thermal buckling and sundry design problems. This book is of value to mechanical engineers, and to mechanical engineering teachers and students.

Wind farms and other renewable energy sources are characterized by the high unpredictability of generated power as a function of time. When the wind velocity decreases, the power generation diminishes rapidly. To offset the loss of power in the energy system, thermal power plants should be designed for quick start-ups and shutdowns, i.e., the flexibility of thermal power units should be improved. The pressure and temperature of the working fluid in the boiler should be increased quickly, so as to shorten the start-up of the boiler. The subject of the book is inverse heat transfer problems occurring in the monitoring of thermal stress in pressurized thick-walled components. New methods of determining the optimum time variations of fluid temperature during heating and cooling of the pressure parts in thermal power plants are presented. A new technique for measuring the transient temperature of fluid flowing in the pipeline are also presented. Numerous examples that illustrate the practical application of theoretical methods developed are presented as well. The book is meant for engineers, researchers, and scientists. It can also benefit the students of technical universities. The book may be helpful to manufacturers of large power boilers and users of thermal power plants, both conventional and nuclear.

This is the fourth volume of the handbook Thermal Stresses. Following the principles established when the first volume was published in 1986, the fourth volume consists of six separate chapters prepared by specialists in the field. Each chapter is devoted to a different topic in the area of Thermal Stresses. Many results have been published for the first time in Thermal Stresses IV. The exposition of the material is on the state-of-the art level, which should be appropriate for graduate students, researchers, and engineers specializing in the field of stress analysis. In most cases the material is presented with some historical perspective. A large number of references provided will allow the readers to augment their knowledge, after studying a particular chapter.
