RAYLEIGH WAVE DISPERSION IN THE COLD-WORKED LAYER OF USED RAILROAD RAIL

The first shear mode (Sezawa mode) and the fundamental Rayleigh mode have been identified as they propagated through the work-hardened layer on the top surface of used, steel railroad rail. Longitudinal wave velocities and densities are very nearly equal for the work-hardened layer and the subadjacent layer. The ratio of shear wave velocity in the upper layer to that in the subadjacent layer is near to 0.95. Experimental data obtained at several frequencies (0.5-2.0 MHz) showed good agreement with expected velocities for a layer thickness ranging from 3 to 5 mm.
