Fatigue failures in structural members originate from extremely localized phenomena. Therefore, fatigue assessment should be based as far as possible on the local parameters of geometry, loading, and material.
This book reviews the available knowledge on local approaches to fatigue assessment of welded joints, gathers the data necessary for their practical application, and demonstrates the power of the local concept by way of examples from research and industry. 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 aluminum alloys are considered.
Key Features:
- Serves as a reference for researchers in the field
- Supplement to popular earlier work "Fatigue Strength" by D. Radaj
- Serves as guide to students and experts who are doubtful with regard to the theoretical fundamentals and experimental validations of these methods
