Acoustic bulletin, Vol. 12 ¹ 2, (2009) |
| The paper deals with analyzing the resonance features on the inhomogeneous waves at antisymmetric vibrations of a half-layer with free lateral surfaces and free edge, depending on the Poisson's ratio. The resonant increase of the amplitude's module of the first inhomogeneous wave has been found in that range where two propagating modes exist. The phase of the complex amplitude of the first inhomogeneous wave changes its sign when passing through the resonant frequency. The resonant behavior of the first inhomogeneous wave is observed not for all Poisson's ratios. |
