摘要
Characteristics of surface wave propagation along the edge of semi-infinite plates (edge waves) are investigated by means of the semi-exact method proposed by the present authors. First, the characteristics of edge waves for semi-infinite isotropic plates are calculated and the results are compared with those obtained by other published approximate theories and by the FEM. The semi-exact method is found to completely describe symmetric and antisymmetric modes of edge wave propagation. An approximate relation between the velocity of energy propagation and Poisson's ratio is obtained for the first antisymmetric mode in the high frequency range. Next, the frequency spectra are discussed for a semi-infinite unidirectionally reinforced carbon/epoxy laminated plate and for a hybrid composite laminated plate which consists of carbon/epoxy and glass/epoxy layers.
