Keywords: railway rail, axial force, nondestructive inspection, X-ray stress measurement method, cos-alpha method, tensile testing machine, full-scale test.

Summary

The study, described in this paper, examines the application of X-rays to evaluate rail axial force. The X-ray stress method measures the strain of a crystalline material using a noncontact, nondestructive technique. When a load is applied to the material, the lattice spacing of the crystal changes and the spacing is measured by X-ray diffraction. A simple cos-alpha X-ray analysis, developed in Japan, measures the stress within tens of seconds and can be used to make measurements in the field. A laboratory tensile testing machine measured the stress on an actual rail. This value was compared with that obtained by the X-ray stress measurements. The X-ray apparatus combined with the cos-alpha method was shown to measure the rail axial force in rails accurately.
