| Abstract |
| | Experiments show Love wave generation along the top surface of used railroad rail JIS50-N where the shear wave velocity has been slightly reduced by the cold working of wheel passage for years. The radiofrequency pulses used in the experiments have approx 10 mu s duration and a relatively narrow frequency spectrum. The group velocity for the Love wave is found to have a strong dependence on the carrier frequency over the tested range of 0.45-3.1 MHz. Application of the seismological one-layered model to the experimental measurements yields an NDE technique for the elastic properties and the thickness of the cold worked surface layer. The results are interpreted on the basis of a destructive observation by micro-Vickers hardness testing.-AA |
