The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyses the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimised in the design process. Part one concentrates on analysing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part two, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modelling residual stresses in predicting the service life of structures. With its distinguished editor and international team of contributors, Fracture and fatigue of welded joints and structures is an essential reference for mechanical, structural and welding engineers, as well as those in the academic sector with a research interest in the field. Analyses the processes and causes of fracture and fatigue, focusing predicting and minimising the failure of welded joints in the design process Assesses the fracture of welded joints and structure featuring constraint-based fracture mechanics for predicting joint failure Explores specific considerations in fatigue analysis including the assessment of local stresses in welded joints and fatigue design rules for welded structures

As critically important as welding is to a wide spectrum of manufacturing, construction, and repair, it is not without its problems. Those dependent on welding know only too well how easy it is to find information on the host of available processes and on the essential metallurgy that can enable success, but how frustratingly difficult it can be to find guidance on solving problems that sooner or later arise with welding, welds, or weldments. Here for the first time is the book those that practice and/or depend upon welding have needed and awaited. A Practical Guide to Welding Solutions addresses the numerous technical and material-specific issues that can interfere with success. Renowned industrial and academic welding expert and prolific author and speaker Robert W. Messler, Jr. guides readers to the solutions they seek with a well-organized search based on how a problem manifests itself (i.e., as distortion, defect, or appearance), where it appears (i.e., in the fusion zone, heat-affected zone, or base metal), or in which materials or situations. True to form, Dr. Messler makes readers feel he is speaking directly to them with his clear conversational but unambiguous writing style. Figures, tables and footnotes complement and augment the text suited to welding neophytes and veterans alike.

These recommendations present general methods for the assessment of fatigue damage in welded components, which may affect the limit states of a structure, such as ultimate limit state and serviceability limited state. Fatigue resistance data is given for welded components made of wrought or extruded products of ferritic/pearlitic or banitic structural steels up to fy = 700 Mpa and of aluminium alloys commonly used for welded structures.

The Welding Engineer's Guide to Fracture and Fatigue provides an essential introduction to fracture and fatigue and the assessment of these failure modes, through to the level of knowledge that would be expected of a qualified welding engineer. Part one covers the basic principles of weld fracture and fatigue. It begins with a review of the design of engineered structures, provides descriptions of typical welding defects and how these defects behave in structures undergoing static and cyclical loading, and explains the range of failure modes. Part two then explains how to detect and assess defects using fitness for service assessment procedures. Throughout, the book assumes no prior knowledge and explains concepts from first principles.

Local approaches to fatigue assessment are used to predict the structural durability of welded joints, to optimise their design and to evaluate unforeseen joint failures. This standard work provides a systematic survey of the principles and practical applications of the various methods. It covers the hot spot structural stress approach to fatigue in general, the notch stress and notch strain approach to crack initiation and the fracture mechanics approach to crack propagation. Seam-welded and spot-welded joints in structural steels and aluminium alloys are also considered. This completely reworked second edition takes into account the tremendous progress in understanding and applying local approaches which has been achieved in the last decade. It is a standard reference for designers, structural analysts and testing engineers who are responsible for the fatigue-resistant in-service behaviour of welded structures. Completely reworked second edition of a standard work providing a systematic survey of the principles and practical applications of the various methods Covers the hot spot structural stress approach to fatigue in general, the notch stress and notch strain approach to crack initiation and the fracture mechanics approach to crack propagation.

Welding and Joining of Advanced High Strength Steels (AHSS): The Automotive Industry discusses the ways advanced high strength steels (AHSS) are key to weight reduction in sectors such as automotive engineering. It includes a discussion on how welding can alter the microstructure in the heat affected zone, producing either excessive hardening or softening, and how these local changes create potential weaknesses that can lead to failure. This text reviews the range of welding and other joining technologies for AHSS and how they can be best used to maximize the potential of AHSS. Reviews the properties and manufacturing techniques of advanced high strength steels (AHSS) Examines welding processes, performance, and fatigue in AHSS Focuses on AHSS welding and joining within the automotive industry

This report is the result of a major study on the influence of both main plate thickness and of attachment size on the fatigue strength of joints with transverse non-load-carrying fillet welds. In particular, it defines the extent to which the size of the attachment might influence the thickness effect in such joints. Through a whole range of different tests, the study confirms that the present thickness effect correction for certain types of joint is too severe.
