Measurement of Rayleigh Wave Attenuation in Granite Using Laser Ultrasonics

Abstract

The use of ultrasonic waves to characterize a material requires the measurement of a variety of wave attributes such as phase velocity and attenuation. For example, experimentally measured phase velocities can be used to calculate elastic constants (such as the Lame constants λ and μ), while attenuation results can be used to characterize the distribution).
