Determination of relationship between Rayleigh wave velocity and stress with laser Doppler velocimeter

A non-contact measurement technique of Rayleigh wave velocity is proposed. In the non-contact measurement system, a laser Doppler velocimeter is used to determine wave motions. With above technique, the relationship between Rayleigh wave velocity and stress for an aluminum alloy 5052 and steel SS400 is determined, and the results are in good agreement with that obtained by contact measurement method.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
