Non-Destructive Methods to Appreciate the State of Stesses and Cracks in Wheels and Railroads

The paper proposes three non-destructive experimental methods in order to establish some criterions for the maintenance inspections of the railroads.. The first experimental method consists in drilling the railroad in different areas (head, basement and core of the rail profile).The bending capa...
