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.

Due to its speed, low energy requirements, and the fact that it does not require a pre-drilled hole, the technique of self-piercing riveting (SPR) has been increasingly adopted by many industries as a high-speed mechanical fastening technique for the joining of sheet material components. Self-piercing riveting comprehensively reviews the process, equipment, and corrosion behaviour of self-piercing riveting, and also describes the process of evaluation and modelling of strength of self-piercing riveted joints, quality control methods and non-destructive testing. Part one provides an extensive overview of the properties of self-piercing riveting. Chapters in this section review the mechanical strength, fatigue, and corrosion behaviour of self-piercing riveted joints. The second part of the book outlines the processing and applications of SPRs, and describes the dynamic strength evaluation/crashworthiness of SPRs, and the modelling of strength of self-piercing riveted joints, before going on to discuss the assessment of the suitability of materials for self-piercing riveting. The concluding chapters describe the quality control and non-destructive testing of self-piercing riveted joints, optimization of the strength of self-piercing rivets, and provides an overview of self-piercing rivets in the automotive industry and the applications of self-piercing riveting in automated vehicle construction.
