In this paper, an analytical approach for mechanical buckling analysis of moderately thick functionaly graded (FG) rectangular plates is presented. The equilibrium equations are derived according to the first order shear deformation theory (FSDT). Using Navier's type solution these equations are solvedfor the functionally graded rectangular plate with simply supported under mechanical loading. The excellent accuracy of the present analytical solution is confirmed by making some comparisons of the present results with those available in the literature. Furthermore, the effects of power of functionally graded material, plate thickness, aspect ratio on the critical buckling load of the functionally graded rectangular plate are studied<\div>

In this paper, free vibration analysis of functionally graded(FG) beams resting on Winkler foundation are investigated using first order shear deformation theory and. Material properties of the beam change in the thickness direction according to power–law distributions. The governing equations and the related boundary conditions are derived using the principal of the minimum total potential energy. The Navier–type solution is used for simply–supported boundary conditions, and exact formulas are proposed for the fundamental frequencies. In order to establish the accuracy of the present formulation and results, t he n atural f requencies are obtained, a nd c ompared w ith t he p ublished r esults available in the literature. Good agreement is observed. Numerical results are presented to investigate the influences the different material distributions and foundation stiffness on the free vibration behavior of FG beams.<\div>
