This paper deals with the thermo mechanical vibration analysis of functionally graded ceramic metal (FGM) plates. Theoretical formulations are based on higher order shear deformation theory using finite element method. It is assumed that the mechanical properties are temperature dependent and graded in the thickness direction of the plate in terms of volume fractions of the constituents. The temperature field is varied along the thickness direction of the plate and is kept constant over the plate surface. The fundamental equations for the FGM plate are derived by applying traction free boundary condition at the top and bottom surfaces using variational approach. A nine noded c⁰ continuous isoparametric finite element is employed with ten degrees of freedom per node to accomplish the results. convergence and comparison studies has been carried out to check for efficiency of the model prepared.
The numerical results are obtained for the different thickness ratios volume fraction index and temperature rise for different boundary conditions results conclude that the temperature field induced affect the vibrational characteristics.
