Abstract

The fundamental frequency of an axisymmetric clamped circular bimodulus thick plate subjected to a combination of a pure bending stress and extensional stress in the plane of the plate is investigated. The governing equations which are obtained by using the average stress method are solved by the Galerkin method. Natural frequencies are compared with the previous results of Irie et al. for ordinary thick plates. The effects of various parameters on the natural frequencies and neutral surface locations are studied. The bimodulus properties are shown to reduce the frequency coefficient OMEGA , significantly.
