Research on rail steel repair with Stellite 6 powder using a laser metal deposition process was investigated and reported in this study. Rail failures due to excessive wear and other rail head defects can increase the risk of operation and reliabilit

Stress concentration induced by geometry irregularity was found near the weld toe of rail welded joints, leading to high risk of fatigue crack initiation. In this research, an integrated fatigue assessment method of rail welds based on the 3D dynamic

Thermite welded joints are commonly applied in running rails and any failures related to it will result in delay of time schedule or safety issues. The detection and monitoring of these joints are essential for pre-emptive maintenance and therefore t
This study investigates the structural fatigue crack growth behavior of observed transverse surface cracks in rail steel and thermite weld subjected to in-plane and out-of-plane loading. Stress Intensity Factor (SIFs) solutions were derived from fini

This study developed a structural fatigue life prediction model of thermite welded rail joints taking account of the weld-induced residual stress and stress relaxation by external cyclic load. A three-dimensional finite element model including the se
