Fatigue and Fracture of Welded Structures

Dear Colleagues,

Welding technology, as a highly durable, reliable, and cost-effective connection technique, is widely used in aerospace, rail transit, and other energy industries. The context for this Special Issue lies in the increasing demand for high-performance and durable welded structures. As structures are subjected to complex loading conditions and environmental factors, the occurrence of fatigue and fractures can lead to catastrophic failures. Therefore, research on the fatigue and fracture of welded structures is essential to develop effective prevention and mitigation strategies.

Over the past few decades, there have been extensive reports on the mechanical properties and deformation behaviours of welded structures. However, most of the current research primarily concentrates on common mechanical properties and deformation. There is a lack of research on the mechanical behaviour of welded structures in complex mechanical environments, especially in clarifying fractures, fatigue crack propagation, fatigue damage, and failure mechanisms via advanced characterization methods and numerical analysis models.

We are pleased to introduce this Special Issue dedicated to the exploration of the "Fatigue and Fracture of Welded Structures". This Special Issue aims to provide a platform for researchers to share their latest findings and advancements in the study of the fatigue and fracture of welded structures.

We hope to promote interdisciplinary research, encourage the development of new testing and analysis methods, and deepen our understanding of fatigue and fracture mechanisms in welded structures. Potential authors are invited to submit original research articles, review papers, and case studies that address topics such as welding processes and their effects on fatigue and fracture, fatigue life prediction models, the fracture mechanics of welded joints, and innovative materials and technologies for improving the fatigue and fracture resistance of welded structures. By bringing together the latest research in this field, this Special Issue will contribute to the advancement of knowledge and the development of more reliable welded structures.

We look forward to receiving your contributions.
