Acoustoelastic Effect for Rayleigh Surface Waves in the Presence of a Nonuniform Stress Field

Abstract

The acoustoelastic effect for Rayleigh waves on the inner diameter of a right circular steel cylinder was investigated. The velocity dependence on stress was studied as a function of frequency. As expected, the change in velocity was proportional to the applied stress at the surface. As a result of the nonuniformity of the applied stress field, however, the proportionality constant was expected to depend on frequency. Such a frequency dependence was observed and interpreted in light of existing theoretical predictions for the velocity behavior of Rayleigh waves in the presence of a nonuniform stress field. Keywords: Acoustoelastic effect, Rayleigh waves, Surface waves, Ultrasonic, Stress, Acoustic waves, Steel.
