A high specific stiffness, high specific strength, and tailoring the properties for specific application have attracted the attention of the researchers to work in the field of laminated composites and Sandwich structures. Rapid use of these laminated composites and Sandwich structures necessitated the development of new theories that suitable for the bending, buckling and vibration analysis. Many articles were published on free vibration of beams, plates, shells laminated composites and sandwich structures. In this article, a review on free vibration analysis of shear deformable isotropic beams, plates, shells, laminated composites and sandwich structures based on various theories and the exact solution is presented. In addition to this, the literature on finite element modeling of beams, plates, shells laminated composites and sandwich structures based on classical and refined theories is also reviewed. The present article is an attempt to review the available literature, made in the past few decades on free flexural vibration response of Fiber Metal laminated Composites and Sandwich panels using different analytical models, numerical techniques, and experimental methods.

“…The simply supported boundary conditions for the uniformly distributed load can be written as: (29) By applying the boundary conditions above, one can fully determine the 10 unknown constants. The exact solution of the bending and the shear deflection can be written as: (30) The coefficients and are shown in the Appendix (A2).…”

“…Compared with the FSDT, the RPT leads to a parabolic shear deformation distribution across the thickness direction thus automatically satisfy the traction free conditions. Therefore, it not only reduces the number of unknowns but also shows a clearer physical meaning and provides more accurate solutions than FSDT [30].…”

An aluminum/high-density polyethylene (HDPE) functionally graded material (FGM) has been fabricated as a key component of a multifunctional building envelope for energy efficiency and sustainability. Because of the gradual phase change of aluminum and HDPE across the thickness direction, when a free-standing FGM panel is subjected to a temperature change, it will exhibit considerable curling deformation, which causes challenges to assemble the FGM panel into a flat multifunctional roofing panel and also to assure structural integrity under cyclic temperature change. Therefore, it is crucial to predict the thermo-mechanical behavior of the FGM panel. For this purpose, an axisymmetric refined plate theory was developed in this study for a circular FGM panel subjected to thermo-elastic loading classic. The theoretical solutions are verified with experimental results, it demonstrates that the presented solution can accurately predict the thermo-mechanical behavior of the developed FGM panel and be used in the design of the proposed solar panel.

“…In addition, their mechanical behavior can be optimized by ingeniously choosing the material type and composite pattern. A typical application is the sandwich structures [1][2][3][4][5], usually composed of two stiff face layers and a relatively soft core layer, bonded together by the adhesive. It is known that the interfacial damage exists widely in sandwich structures due to the discontinuity of material property at the interface.…”

In this work, analytical solution of simply supported sandwich arches considering permeation effect of adhesives is presented. e permeation layer is described by the functionally graded material, exponentially graded in the radial direction. e stresses and deformations of each layer are based on the two-dimensional (2D) elasticity theory in the polar coordinate. e governing equations of the arch are solved by the layer-wise method, which turns the differential equations with variable coefficients into constant coefficients. e solution can be obtained efficiently by means of the recursive matrix method, especially for the arch with many layers. e present solution agrees well with the finite element solution with a fine mesh, while the finite element method is time consuming in mesh division and calculation. e one-dimensional (1D) solution based on the Euler-Bernoulli theory is close to the present one; however, the error increases as the arch becomes thick. e effect of permeation layer thickness on the stresses is studied. It is indicated that the stress distributions tend to be smooth along the radial direction as the permeation layer thickness increases.
