Many review articles were published on free vibration and buckling of laminated composites, sandwich plates, and shells. The present article reviews the literature on the buckling and free vibration analysis of shear deformable isotropic and laminated composite sandwich plates and shells using various methods available for plates in the past few decades. Various theories, finite element modeling, and experimentations have been reported for the analysis of sandwich plates and shells. Few papers on functionally graded material plates, plates with smart skin (electrorheological, magnetorheological, and piezoelectric), and also viscoelastic materials were also reviewed. The scope for future research on sandwich plates and shells was also accessed.

“…Verifications are made for both the buckling finite element code and also the results from the genetic algorithm by comparisons to the results available in literature. Results are presented in terms of stacking sequence of fibers in the face sheets and core to face sheet thickness ratio [2]. Z.

Despite of laminate or sandwich composite materials structure, mechanical behavior can estimate by methods or analytical relations like laminates classical theory according factors just like mechanical properties, fiber percentage, and product methods and etc. but generally these estimates are far from experimental results. This paper investigates about influence of product methods and different cores on buckling and post buckling behaviors of sandwich panels. Each panel was built by to quit different product method, hand layup or vacuum bag infusion procedure with different core. To build the panels an effort had made to choice materials which have usage in marine industry, special for high speed boats. Sandwich panels have 150×450 mm 2 dimensions and one simply support and one clamed support. After tests, numerical models results which drive from finite element software are compared with experimental data. The results represent that combined model is suitable for simulate buckling and post buckling behavior. After chosen the software model, different parameters were evaluated whom the link element has the most efficacy on numerical results.

“…The classic plate theory was used to model the thin elastic layers, whereas Reddy’s third-order shear deformation theory was employed for the core. Design optimisation of sandwich cylindrical panels using a finite-element modelling and analysis was performed by Abouhamzeh and Sadighi [14]. The structure of sandwich panels with isotropic and orthotropic cores was optimised for the buckling strength.…”

“…Widespread use of the composite sandwich cylindrical panels in heavily loaded structures stimulates further interest to the investigations of their buckling behaviour. Results of recent studies in this area are presented in the articles published by Kasperska and Ostwald [9], Szyca et al [10], Pineda et al [11], Dey and Ramachandra [12], Moita et al [13], Abouhamzeh and Sadighi [14] and Muc et al [15]. Kasperska and Ostwald [9] presented design optimisation of sandwich panels, in which one of the constraints in the optimisation problem formulation was imposed in the form of a stability condition.…”

Analytical solution of the buckling problem for a composite cylindrical sandwich panel subjected to axial load is presented in the paper. The straight longitudinal edges of the panel are fully clamped, and the curved sides are simply supported. This loading results in the biaxial compression of the panel. The buckling analysis is performed using the equations of the engineering theory of laminated cylindrical shells, taking into account the transverse shear deformations. The system of linearized buckling equations is derived in terms of unknown displacements, deflection, and angles of rotation of the normal to the middle surface of the panel. The equations are solved by combining the Levy and Galerkin methods. In this approach, the deformed panel was approximated by trigonometry and beam functions. The analytical formula for the critical load has been derived and verified using finite-element analysis. Based on this formula, the influence of Poisson’s effect on the value of buckling load has been studied. Design application of the formula is demonstrated for a specified value of the critical load.
