“…The mechanical properties of the plate are assumed to vary continuously in the thickness direction by a simple power-law distribution in terms of the volume fractions of the constituents. 63 The effects of rotatory inertia considered in the sinusoidal shear deformation plate theory are presented. The present sinusoidal theory contains the same dependent unknowns as FSDT and third-order shear deformation theory but accounts for according to a cosine law distribution of the transverse shear strains through the thickness of the plate.…”

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.

“…When these structures are subjected to compressive loads, there is a possibility of buckling in them. [1][2][3][4][5][6][7][8][9][10] In many engineering applications, composite structures may be exposed to hot and wet environments. Since the hygrothermal environments play an important role in the behavior of composite structures, the effects of two parameters of moisture and heat should be considered in the analysis of these structures.…”

The present work attempts to investigate the influence of hygrothermal environments on the buckling of soft-core sandwich plates with laminated composite face sheets. The stability equations are derived based on piecewise low-order shear deformation theory (PLSDT) and then solved using different methods, depending on the boundary conditions. For fully simply supported sandwich plates, an analytical method is developed which results in some closed-form solutions. For sandwich plates with two parallel simply supported edges and two clamped edges, a semi-analytical solution is established using one-dimensional generalized differential quadrature (GDQ) technique. Finally, for fully clamped sandwich plates, twodimensional GDQ approach is applied to the governing equations. To validate the results of proposed methods, a comparative study with various examples is carried out verifying that the methods in the present work can accurately predict the buckling load of sandwich plates in hot and wet environments. Then, a comprehensive parametric study is performed to show the effects of temperature and moisture content on the buckling of sandwich plates for different parameters such as length-to-thickness ratio, core thickness, and boundary conditions. It is concluded that both temperature and moisture content have significant influences on the buckling behavior of sandwich plates.

“…While all the above references are with respect to elasticity solutions, it should be noted that the first-order shear deformation theory (FSDT) as well as higher-order theories have also been extensively employed for the static, dynamic and stability analysis of sandwich plates with core or facesheets graded in the thickness direction [23–28, for example]. These serve to show the importance of capturing non-classical effects in such sandwich plates.…”

A convergent series solution based on the theory of elasticity is presented for bending of a sandwich plate strip with an isotropic homogeneous core and composite orthotropic facesheets with variable fibre volume fraction in the in-plane direction. The accuracy of first-order shear deformation theory is assessed against this benchmark solution. Further, it is shown that the benefit of using functionally graded material facesheets depends critically on the span-to-thickness ratio of the plate.
