In this parametric study, the buckling analysis of symmetrically laminated rectangular thin plates subjected to biaxial compression is presented. The simply supported boundary condition is considered at the edges of the symmetrically laminated quasi-isotropic, crossply and angle-ply plates. The Rayleigh-Ritz Method is used to specify the critical buckling load of the plates based on the Classical Laminated Plate Theory (CLPT). A convergence study is achieved by increasing the number of parameters of assumed shape function. Validation of isotropic case is verified. The effects of the lamination types, plate aspect ratios (a/b, b/a) and thickness on the critical buckling load of the laminated plates under bi-axial compression were then investigated. The results were compared with Finite Element Method (FEM) solutions performed by ANSYS software package and fairly good agreement is obtained. Non-dimensional results were tabulated and presented for practical use for designers.

In the notched structures, to achieve maximum buckling resistance in comparison with structural weight, the optimal design of a stiffener is very important. In this research, after a review of the existing literature, nonlinear buckling behavior of composite plates containing the cutout with three different designs of stringer was investigated. The considered stiffeners are planer, longitudinal, and ring types. The buckling experiments were carried out on the stiffened plates containing a circular notch. Moreover, to achieve an efficient prediction of the buckling in the stiffened laminate with the hole, a finite strip method is developed based on the Airy stress function and von Karman’s large deformation equations. Studies show that there is a good agreement between the postbuckling behaviors derived from developed finite strip method with experimental results. Fast convergence of the considered finite strip method compared with the finite element results shows its efficiency for prediction of buckling behavior in laminated composites. The results show that the buckling load-bearing capacities of perforated plates with a longitudinal and planer stiffener are higher compared with the other stiffener, respectively. The detailed parametric study on the effects of thickness of the plate and stiffener and opening diameter on buckling behavior was performed using experiments and modeling.

“…Developments of new materials such as functionally graded materials (FGMs), however, have necessitated more research in this area. It is observed from the literature that studies involving stability (in terms of buckling) characteristics of FGM plates subjected to thermal [3-25, 46, 47, 52], mechanical loading [26][27][28][29][30][31][32][33][34][35], or combinations of [20,[36][37][38][39][40][41][42] based on deterministic analysis have received greater attention [43][44][45].…”

“…The same remark is observed in. [6,[11][12][13][14][28][29][30][31][32][33][34][35] The values of the critical temperature differences calculated by using the four variable refined plate theory are lower than those calculated by using the classical plate theory. In conclusion, the transverse shear deformation has some effect on the buckling temperature difference.…”

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.
