Description
Summary: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 capacity of the railroad is not adulterated after the drilling procedure . The residual surface stresses vanished around the hole, the deformations along 3 directions are measured with a rosette transducer and the values of the previous residual stresses will be calculated . The periodical ultrasonic inspection has been performed with a portable ultrasonic crack detector.
