Woodhead Publishing Fatigue Assessment of Welded Joints by Local Approaches (Series in Welding and Other Joining Technologies) (Woodhead Publishing Series in Welding and Other Joining Technologies)

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 completely reworked second edition of a 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. Key Features: 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; written by a distinguished team of authors; a standard reference for designers, structural analysts and testing engineers.
