MEASUREMENT OF ACOUSTOELASTIC AND THIRD-ORDER ELASTIC CONSTANTS FOR RAIL STEEL

Measurements of the stress-induced changes in ultrasonic wave speeds in steels typically used in railroad rails are presented. All of the five possible relative changes in wave speeds for a unaxial state of stress have been determined and agree, to within the limits of accuracy of the measurement, with the second-order theory of Hughes and Kelly. The third-order elastic constants are calculated from the acoustoelastic data.
