摘要:
Thermoelastic attenuation of Rayleigh waves is larger than that of bulk waves because heat is conducted not only in the propagation direction, but also normal to the surface. This attenuation is further enhanced if the thermal expansivity is a function of depth below the surface. Expressions are obtained for the attenuation and some experimental data on Rayleigh wave attenuation is discussed.
