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 finite element method (FEM) and onsite strain mon...
