| Abstract |
| | The US National Institute of Standards and Technology, Fracture and Deformation Division is developing a system aimed at using relatively low frequency Rayleigh waves generated by electromagnetic-acoustic transducers (EMATs) for the roll-by crack inspection of railroad wheels. The EMAT device, which is inserted into a recess cut out of the rail, produces a simplified, low-noise signal which is easy to interpret, and its non-contact nature eliminates the need for ultrasonic couplants. With the development of a signal processing and analysis system, field tests at the Transportation Test Centre in Colorado should soon be possible. 10 ref.-S.M.F. |
