In this paper the dispersion of the generalized Rayleigh wave propagation in
the non-prestressed half-plane covered with pre-stretched two layers under
complete contact conditions is investigated by 3-D linearized theory of
elasticity. The layers and the half-plane are assumed that elastic,
homogeneous, isotropic, and the complete contact conditions are existed.
The inter phase zone between the upper layer and half-plane is modeled by
this second layer. The purpose of the investigation is the determination on
the effect of the existence of the second layer to the considered
generalized Rayleigh wave propagation velocity. For this purpose, firstly
the same materials were selected for both layers and the results obtained in
previous studies for a single layer in the literature were verified, the
accuracy of the modeling was shown, and then the effect of the second layer
on the considered problem was shown by selecting the different materials and
applying different initial pre-stresses. Consequently, the present study
can be considered as the investigation of the existence of the inter phase
zone which is characteristic one for the composite materials to the
dispersion of the generalized Rayleigh wave propagation. Numerical results
obtained and discussed.
