Thermal Stress Resistance of Materials
This book deals with the problem of a bearing capacity and fracture of thermally loaded materials. The treatise is based on extensive experimental and technological data of materials-development processes for high-temperature nuclear reactors and aerospace nuclear-rocket engines. New regularities and irregularities of fracture at various modes of local and combined thermal loading using electron-beam, induction and ionic-beam technique of heating, and also with traditional methods of measuring the thermal stress resistance are discussed. New criteria for the estimation of the bearing capacity of bodies in inhomogeneous fields of thermal and residual stresses are developed on the basis of fracture mechanics. Changes in the thermal stress resistance of carbides (ZrC, NbC, and SiC), graphite, Si3N4, Y2O3, Sc2O3 Al2O3 and single crystals of sapphire are considered. Possible technological methods for the improvement of thermal stress resistance are also presented.
Theory of Thermomechanical Processes in Welding
This book presents a modern viewpoint of welding thermomechanics and provides a unified and systematic continuum approach for engineers and applied physicists working on the modelling of welding processes. The theory presented includes developments in the areas of welding thermodynamics, thermoplasticity and numerical methods. The book describes the calculation of thermal stresses in welding structures, the theory of heat conduction in welding, and the basic equations of thermoplasticity, then applies the concepts to solutions of thermoplasticity problems and to thermal stresses in arc welding, laser welding, spot welding, electroslag welding and friction welding.
