Repeated wheel–rail interaction under millions of load cycles causes rolling contact fatigue, plastic deformation, and long-term rail degradation. Increasing axle loads, speeds, and traffic demand require an understanding of how rail steels respond under dynamic loading. This study compares the mechanical and fatigue b...
