The present paper investigates the thermal stability analysis of functionally graded material plates subjected to three types of thermal loadings, namely; uniform temperature rise, linear temperature rise and non-linear temperature rise through the thickness, using a novel simple refined theory. The theory, which has strong similarity with classical plate theory in many aspects, accounts for a quadratic variation of the transverse shear strains across the thickness and satisfies the zero traction boundary conditions on the top and bottom surfaces of the plate without using shear correction factors. Material properties are varied continuously in the thickness direction according to a simple power law distribution. A buckling analysis of a functionally graded plate under there types of thermal loads is carried out and results in closed-form solutions thermal stability analysis of functionally graded plates using simple refined plate theory. The influence of various factors such as gradient index, temperature loads, thickness and aspect ratios are carefully studied. The results are verified with the known data in the literature. This theory is seen to behave well, and the results of the sample problem show good agreement with the literature values as seen from the validation checks.

“…After obtaining the converged postbuckling de#ection, the vibration analysis of thermopiezoelectrically buckled plates can be performed by solving equation (23) as a generalized eigenvalue problem as follows: [20]. The critical temperature rise of isotropic square plates with all simply supported and clamped edges subjected to constant temperature distribution has been calculated and compared with previous results in Table 1.…”

“…The displacement field of a rectangular shear deformable plate can be expressed as (1) From the theory of large displacement, the strain-displacement relations can be written as (2a) and (2b) where () ,x and () ,y represent partial differentiation with respect to x and y. The relationship between stress resultants and the strain terms for the laminated plate may be written as (3) and the shear resultants may be written as (4) where stretching, stretching-bending and bending stiffnesses are defined as (5) where [Q ij ] k represents transformed plane stress reduced stiffness matrix of the kth lamina, which is a function of ply-angles (θ 1 , θ 2 , θ 3 . .…”

Buckling temperatures of graphite/epoxy laminated composite plates are maximized for a given total thickness considering fiber-directions and relative thicknesses of layers as design variables. Thermal buckling analysis is carried out using the finite element method with 4 node shear deformable plate element, while genetic algorithm (GA) is employed to optimize as many as ten variables for the five layered plates. In addition to traditional three-operator approach, i.e., reproduction, crossover and mutation, other variants of GAs such as the elitist model, two-point crossover models are also discussed. The study includes composite plates of three different aspect ratios, two support conditions and three different numbers of layers. The presented results reveal that the buckling loads can be increased significantly with appropriately orienting the fiber directions and varying the thickness of different layers. The authors also recommend the judicious selection of specific thicknesses and fiber orientations needed for the practical implementation highlighting the importance of their theoretical values so that they may also be made available in near future for fabrication.
