This paper studies Nonlinear free vibration of thin circular plates with clamped immovable boundary under thermal loading. A steady-state temperature, field, characterized by constant surface temperatures measured from stress free temperature, is considered. The basic governing differential equations have been derived in the von Karman sense in terms of displacement components and solved with the help of Galerkin Procedure. Parametric studies have been presented to understand the Nonlinear free vibrations of thin isotropic elastic circular plates under thermal loading. This study reveals some interesting Nonlinear dynamic features of such structures which may prove useful to the designers.
