Dynamic Response of Sandwich Bottom Plate of Rigid Fluid Container Resting on Elastic Foundation

Abstract

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