摘要：

The grid dispersion for a harmonic Rayleigh wave propagating along a straight boundary of a thin elastic solid, modelled by finite elements, is investigated. It is shown that with an increase of dimensionless wavenumber gamma . q, a phase velocity of Rayleigh waves increases from the long wave limit c(R). For sufficiently short waves it follows the dispersion curve referring to quasitransverse waves in an unbounded discretized medium.
