Determination of Stress-Acoustic Coefficients of Rayleigh Wave by Use of Laser Doppler Velocimetry

摘要

In the present paper, 1) a new non-contact ultrasonic stress measurement tech- nique is proposed based on acoustoelasticity, in which ultrasonic wave motion is detected by use of a laser Doppler velocimeter, and 2) the stress-acoustic coefficients of Rayleigh wave for aluminum alloy and structural steel are determined by the technique.
