Abstract:On the basis of the theory of wave propagation in elastic medium and Snell theorem, the propagation characteristics of plane SH wave passing through elastic laminate including two half spaces and multi-layered elastic laminate is analytically studied. The two-dimensional dynamic equations and model of wave propagation are established. An analytical solution to the ratio of the amplitudes of transmitted wave to incident wave is obtained. The propagation of SH wave through two half-space medium including single lamina has been analyzed in detail. The results agree well with the existing ones in references. The comparison of vibration isolation experimental data with the analytical results shows that the analytical solution is valid and the model of wave propagation through elastic laminate is reasonable.
Keywords:plane wave  elastic medium  elastic half-space  interlayer  transmitted wave
