quick question: using my private acoustics library (not a bad one), I tried to find out how the velocity of a Rayleigh wave in steel depends on the temperature of the material. In general, I found a SQRT-relationship with temperature for waves propagating in liquids, but no rules for Rayleigh waves and other waves in solids. Any link or reference would be of great help. Thanks.

Re: Temperature & Rayleigh Waves of temperature effect on Rayleigh type waves: make some experimental estimation of temperature effect on longitudinal and shear waves, estimate a temperature effect on Poisson ratio for a given metal, and calculate the Rayleigh equation taking the result of temperature effect on Poisson ratio. Of course, it is necessary to compare these calculations with experimental data. But I would like to notice that this is not purely Rayleigh wave problem. Probably there are other types of surface waves. If you prove them you can call them "tlh waves".
