| Abstract: | This study
is concerned with the free vibration analysis of thick plates on elastic
foundation using modified Vlasov model. The effects of the subsoil depth,
aspect ratios, the ratio of subsoil depth to span of the plate and the value of
the vertical deformation parameter within the subsoil on the frequency
parameters of plates on elastic foundations are investigated. An eight-noded,
24 degrees of freedom quadrilateral finite element (PBQ8) based on Mindlin
plate theory is used for the analysis. The first six natural frequency
parameters are presented to show the effects of the parameters considered in
the study. It is concluded that the subsoil depth is more effective on the
frequency parameters of plates resting on elastic foundation than the other
parameters considered in this study.
