Abstract |
|
This paper concerns the propagation of Rayleigh waves in compressible prestressed elastic half-spaces. The main aim is to derive formulas for the HV ratio (ellipticity), which is the ratio of the amplitude of the horizontal displacement to the amplitude of the vertical displacement of Rayleigh waves. First, the equation for the HV ratio is obtained using the secular equation and the relation between the HV ratio and the Rayleigh wave velocity. Then, formulas for the HV ratio are derived for a general strain-energy function. They are then specified for some strain-energy functions. Since the HV ratio is a good tool for nondestructively evaluating the prestresses of structures before and during loading, the obtained formulas will be very useful in practical applications. |
