内容記述 | The anisotropy of elastic media, in general, causes drift and uneven distribution of waves in the azimuthal direction. Surface waves in weakly anisotropic media are discussed, focusing attention on the implication of a wave orbit on a transverse plane with drift of waves and azimuthal distribution of wave amplitude. When waves drift rightward(leftward), the orbit tilts leftward(rightward), where the term rightward(leftward) is used in the advancing direction of waves. Under the assumption that uneven distribution of waves in the azimuthal direction is caused only by the anisotropy of media, we find that a surface wave orbit on a transverse plane at the surface tilts rightward(leftward) when the wave amplitude increases(decreases) rightward. It is noted that the above-mentioned drift and uneven distribution of surface waves in the azimuthal direction in anisotropic media can be fundamentally explained by use of the solution of the characteristic equation obtained from stress-free surface conditions. | |||||
