Dispersion of generalized Rayleigh waves in the half-plane covered with pre-stretched two layers under complete contact

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