Generally, welding produces welding deformation and residual stress in the products, which influences the quality and performance of the products. Although many engineers and researchers have made great effort how to control these incidents, they have still remained unresolved. Welding Deformation and Residual Stress Prevention provides a unique computational approach to the prediction of the effects of deformation and residual stress on materials. The goal is to provide engineers and designers with the ability to create their own computational system for predicting and possibly avoiding the problem altogether. The basic theories including "theory of elastic-plastic analysis" and "inherent strain theory" , and analysis procedures are described using a simple three-bar model Online simulation software to perform basic analysis on welding mechanics Examples of strategic methods and procedures are illustrated to have solved various welding-related problems encountered in the process of construction Appendices present data bases for welding residual stresses, temperature dependent material properties, etc.

Research goal of the present monograph is the establishment of an efficient engineering approach, which will include straightforward but accurate simulation models, in order to estimate the residual stress fields of welded joints introduced during welding and their post-weld treatment with High Frequency Hammer Peening. The present subject lies on the intersection of structural engineering, material science and computational mechanics.

The ability to quantify residual stresses induced by welding processes through experimentation or numerical simulation has become, today more than ever, of strategic importance in the context of their application to advanced design. This is an ongoing challenge that commenced many years ago. Recent design criteria endeavour to quantify the effect of residual stresses on fatigue strength of welded joints to allow a more efficient use of materials and a greater reliability of welded structures. The aim of the present book is contributing to these aspects of design through a collection of case-studies that illustrate both standard and advanced experimental and numerical methodologies used to assess the residual stress field in welded joints. The work is intended to be of assistance to designers, industrial engineers and academics who want to deepen their knowledge of this challenging topic.

"The objective of this paper has been to model the cooling process of a simple butt weld using the finite element anlaysis (FEA) method to analyse the formation of welding induced residual stresses. This study involved detailed finite element analysis of the temperatures, stresses, and distortions which occur throughout the welding cycle"--Abstract.

Welding Deformation and Residual Stress Prevention, Second Edition provides readers with both fundamental theoretical knowledge about welding deformation and stress as well as unique computational approaches for predicting and mitigating the effects of deformation and residual stress on materials. This second edition has been updated to include new techniques and applications, outlining advanced finite element methods such as implicit scheme, explicit scheme, and hybrid scheme, and coupling analysis among thermal-metallurgy-mechanics. Non-destructive measurement methods for residual stresses are introduced, such as X-ray diffraction, the indentation technique, the neutron diffraction method, and various synchrotron X-ray diffraction techniques. Destructive measurement techniques are covered as well, such as block cutting for releasing residual stress, blind hole drilling, deep hole drilling, the slit cutting method, sectional contour method, and general inherent strain method. Various industrial applications of the material behavior and computational approaches are featured throughout. Focuses on the underlying theory, practical implementation, analysis and application of measurement techniques for welding deformation and residual stress Includes strategies for mitigation and control of deformation and stress Discusses cutting-edge computational methods for determining welding heat source, thermal process, phase transformation, welding thermal deformation, thermal stress, and residual states Outlines both non-destructive and destructive techniques for measuring residual stress Includes access to a companion site with code, simulation videos and other materials

Finite Element Analysis of Weld Thermal Cycles Using ANSYS aims at educating a young researcher on the transient analysis of welding thermal cycles using ANSYS. It essentially deals with the methods of calculation of the arc heat in a welded component when the analysis is simplified into either a cross sectional analysis or an in-plane analysis. The book covers five different cases involving different welding processes, component geometry, size of the element and dissimilar material properties. A detailed step by step calculation is presented followed by APDL program listing and output charts from ANSYS. Features: Provides useful background information on welding processes, thermal cycles and finite element method Presents calculation procedure for determining the arc heat input in a cross sectional analysis and an in-plane analysis Enables visualization of the arc heat in a FEM model for various positions of the arc Discusses analysis of advanced cases like dissimilar welding and circumferential welding Includes step by step procedure for running the analysis with typical input APDL program listing and output charts from ANSYS.
