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. Content: Front Matter....Pages i-x Description of Welding Deformations....Pages 3-15 Stress Tensor....Pages 17-30 Thermodynamical Background of Welding Processes....Pages 31-50 Motion of Fluids....Pages 51-55 Thermomechanical Behaviour....Pages 57-80 Numerical Methods in Thermomechanics....Pages 83-102 Analytical Solutions of Thermal Problems in Welding....Pages 105-127 Numerical Solutions of Thermal Problems in Welding....Pages 129-144 Thermal Stresses in Welding....Pages 147-155 Welding Deformations....Pages 157-163 Back Matter....Pages 165-174 |
