| چکیده مقاله |
| In this paper, an analytical solution for dynamic interaction of a vertically vibrated rigid foundation located at the interface of a finite liquid layer and a transversely isotropic half-space is presented. The method of potential functions and an integral transform approach, ac-companied by a special contour integration scheme, are adopted to handle the equations of motion and produce the numerical results.. With the aid of Hankel integral transforms, a re-laxed treatment of the mixed-boundary value problem is formulated as dual integral equa-tions, which can be reduced to a Fredholm integral equation of the second kind. The dynamic impedance/compliance function are analytically and numerically evaluated in the general dy-namic case. Finally, a comprehensive evaluation of dynamic impedance function for different materials with different degrees of anisotropy is performed and have been compared with each other. The impedance functions have been evaluated numerically, which can be used in the dynamic fluid-soil-structure-interaction problems. |
