摘要

Recent advances in acoustic microscopy and laser ultrasonics offer surface acoustic waves as a promising means for surface inspection, e.g., for nondestructive evaluation of surface stress. To use Rayleigh waves for measurement of stress in structural metals, the appropriate acoustoelastic coefficients must first be ascertained. For aluminum alloys, however, there has been a lingering problem on the values of Rayleigh-wave acoustoelastic coefficients.
