Nonlinear vibration analysis of laminated plates restingon nonlinear two-parameters elastic foundations
Bekir Akgoz and Omer Civalek

Abstract     [Buy Article]
    In the present manuscript, geometrically nonlinear free vibration analysis of thin laminated plates resting on non-linear elastic foundations is investigated. Winkler-Pasternak type foundation model is used. Governing equations of motions are obtained using the von Karman type nonlinear theory. The method of discrete singular convolution is used to obtain the discretised equations of motion of plates. The effects of plate geometry, boundary conditions, material properties and foundation parameters on nonlinear vibration behavior of plates are presented.
Key Words
    Nonlinear dynamics; free vibration; discrete singular convolution; laminated plates; nonlinear foundation.
