โœฆ Synopsis

The free vibration problem of a system of two rectangular plates connected by a non-homogeneous elastic layer is considered. An integral formulation of the problem by using properties of Green's functions is achieved and by application of a quadrature method to the integral equation, the frequency equation of the combined system is obtained. The comparison of an exact solution with the numerical results obtained by using the presented method for a system of two identical plates is given. The numerical investigations have shown the e!ect of the area size as well as the sti!ness of an elastic layer connecting the plates on the vibration frequencies of the combined systems.
