“…The influence of hygrothermal environment, elastic foundation and nano-scale effect on wave dispersion of FG nanoplates was discussed by Karami et al [20]. Using the refined plate theory, Wang and Zhang [21] investigated buckling behavior of functionally graded nanoplates with nano-porous metal foam. Barati and Shahverdi [22] proposed novel Hamiltonian approach for nonlinear vibration analysis of nonlocal four-variable porous FG nanoplates.…”

This article deals with the analysis of buckling behavior of simply supported porous functionally graded (FG) sandwich nanoplates resting on a Kerr foundation. The material properties of the FG sandwich nanoplate considered to be dependent on temperature and graded continuously along the thickness direction. The analytical equations are obtained using Hamilton's variational principle, by considering the strain energies due to the thermal loads, and higher order nonlocal strain gradient plate theory which captures the shear deformation influences needless of any shear correction factor. Power-law model is adopted to describe continuous variation of material properties of FG sandwich nanoplate. An accurate solution for nonlinear temperature variation across the sandwich nanoplate thickness of is employed taking into account the thermal conductivity, the inhomogeneity parameter and the sandwich schemes. The numerical results computed indicate the influence of volume fraction index, nonlocal parameter, length scale parameter, porosity coefficient, Kerr foundation and temperature difference on the buckling response.

This article aims to investigate free vibration and buckling of functionally graded (FG) nanoporous metal foam (NPMF) nanoshells. The first-order shear deformation (FSD) shell theory is adopted and the theoretical model is formulated by using Mindlin’s most general strain gradient theory, which can derive several well-known simplified models. The symmetric and unsymmetric nanoporosity distributions are considered for the structural composition. Hamilton’s principle is employed to deduce the governing equations as well as the boundary conditions. Then, via the Navier solution technique, an analytical solution for the free vibration and buckling of FG NPMF nanoshells is presented. Afterwards, a detailed parametric analysis is conducted to highlight the effects of the nanoporosity coefficient, nanoporosity distribution, length scale parameter, and geometrical parameters on the mechanical behaviors of FG NPMF nanoshells.

“…One notable area of interest is the development of ultrathin mesoporous nanoplates supported on foam substrates for advanced electrode applications, such as supercapacitors [10]. The study of functionally graded nanoporous metal foam nanoplates has also demonstrated excellent fracture toughness and high electrical conductivities, making them suitable for thin film elements in various engineering applications [11]. Combining nanoporous structures with foam substrates enhances these materials' overall properties and performance.…”

This work examines the vibration characteristics of a sandwich nanosensor plate. The plate comprises a core material of nickel foams, with zinc oxide layers on the top and bottom and a rim layer reinforced with graphene. The study takes into account the surface effect. The study employed the innovative sinusoidal higher-order deformation theory and nonlocal strain gradient elasticity theory. Hamilton's principle obtained the equations governing the motion of a sandwich nanoplate. The Navier method was employed to solve these equations. The sandwich nanosensor plate consists of three different foam variants: a uniform foam model and two symmetric foam models. The work focused on analyzing the sandwich nanoplate's dimensionless fundamental natural frequencies. This investigation examined the impact of three different types of foam, the volumetric ratio of graphene, variations in temperature, nonlocal factors, the ratio of foam void, and electric potential. Additionally, the effect of the presence or absence of surface effects of the sandwich nanoplate on the non-dimensional fundamental natural frequencies was analyzed. Within this context, it was established that the buckling temperature of the nanoplate exhibited an estimated increase of 0.7% due to the surface effect. The research is expected to produce useful discoveries concerning developing and applying nanosensors, transducers, and nanoelectromechanical systems designed to function in high-temperature conditions. It has been noted that the surface impact can be diminished by increasing the stiffness of the foam core layer and supporting rim layers.
