Available in PDF, EPUB and Kindle. Book excerpt: The thermal and mechanical responses of a weldment involving a girth fillet weld are approximated by the finite element method (FEM) and an isothermal ring heat source. Approximately 0.1 ms after the application of the ring heat source, the radial traction at an analytically predicted depth and location within the weldment exceeds the failure strength in tension, followed by fracture. Swelling and elongation of the weldment are in evidence in the general vicinity of the ring heat source. Loading characteristics of a corrective fixture are applied to control the radial traction and dilational motion and to gain design/processing knowledge. The analytical model yields an insight into the physical behavior of the subject weldment during CO2 laser beam welding (LBW).

Book Synopsis Estimation of Thermal Stresses by Finite Element Analysis in a Weld Zone During Atmospheric Cooling by : S. P. Tewari
Download or read book Estimation of Thermal Stresses by Finite Element Analysis in a Weld Zone During Atmospheric Cooling written by S. P. Tewari and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welding is globally used as the most versatile means of joining all commercial metals. In fusion welding, a weldment is locally heated by the welding heat sources. Due to the nonuniform temperature distribution during the thermal cycle, incompatible strain leads to thermal stresses, the main source of problems. Thermal stresses in the weld may lead to formation of hot cracks. Therefore, it becomes necessary to develop a model for the welding process, which would produce not only qualitative but also quantitative information on thermal stresses. In the present work, a finite element simulation of the welding process, yielding the welding induced thermal stresses in rectangular weld pool, is presented.

Book Synopsis Processes and mechanisms of welding residual stress and distortion by : Zhili Feng
Download or read book Processes and mechanisms of welding residual stress and distortion written by Zhili Feng and published by CRC Press. This book was released on 2005-11-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a fabrication technology, welding presents a number of technical challenges to the designer, manufacturer, and end-user of the welded structures. Both weld residual stress and distortion can significantly impair the performance and reliability of the welded structures. They must be properly dealt with during design, fabrication, and in-service use of the welded structures. There have been many significant and exciting developments on the subject in the past ten to fifteen years. Measurement techniques have been improved significantly. More importantly, the development of computational welding mechanics methods has been phenomenal. The progresses in the last decade or so have not only greatly expanded our fundamental understanding of the processes and mechanisms of residual stress and distortion during welding, but also have provided powerful tools to quantitatively determine the detailed residual stress and distortion information for a given welded structure. New techniques for effective residual stress and distortion mitigations and controls have also been applied in different industry sectors. Processes and Mechanisms of Welding Residual Stress and Distortion provides a comprehensive summary on the developments in the subject. It outlines theoretical treatments on heat transfer, solid mechanics and materials behavior that are essential for understanding and determining the welding residual stress and distortion. The approaches for computational methods and analysis methodology are described so that non specialists can follow them. There are chapters devoted to the discussion of various techniques for control and mitigation of residual stress and distortion, and residual stress and distortion results for various typical welded structures are provided. The second half of the book looks at case studies and practical solutions and provides insights into the techniques, challenges, limitations and future trends of each application. This book will not only be useful for advanced analysis of the subject, but also provide sufficient examples and practical solutions for welding engineers. With a panel of leading experts this authoritative book will be a valuable resource for welding engineers and designers as well as academics working in the fields of structural and mechanical engineering.
