Paper Abstract

The paper presents a method for investigating the stress-induced changes in ultrasonic wave speeds at room temperature in rail steel. The pulse echo method is used to measure the wave speed accurately. All of the second-order and thirdorder elastic constants are calculated from the measured acoustoelastic data. A comparison of the strain-induced elastic constant at room temperature is also conducted with previous measurement results.
