APPLICATION OF THE ACOUSTIC-ELASTIC EFFECT TO RAIL STRESS MEASUREMENT

An ultrasonic probe has been designed, evaluated, and shown capable of measuring longitudinal stress changes in railroad rails. The probe utilizes the effect of applied stress on wave velocity (acousto-elastic effect) to determine the stress change. In both laboratory and field evaluations, it has shown that the probe is capable of measuring stress changes.
