Abstract :This study aims to investigate the dynamic behavior of the sandwich type bottom plate, which were not addressed before, attached to a rigid cylindrical fluid container resting on Pasternak type elastic foundation. Thin plate assumptions are incorporated with elastic foundation and plate/foundation interaction system is solved through a mixed finite element formulation. A boundary element procedure is also employed to determine the inertial effect of the involved fluid, which is considered to be ideal. The procedure is tested through the free vibration analysis of homogeneous circular bottom plates and some original results are presented regarding the properties of sandwich plates.
