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. tlh         Reply  Translate  Close   Edouard G. Nesvijski R & D, Senior Scientist TRS Technologies, USA, Joined Jan 2000, 9 Edouard G. Nesvijski R & D, Senior Scientist TRS Technologies, USA, Joined Jan 2000 9 07:13 Feb-23-2000 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". Sincerely, Edouard G.
