The present paper considers the composite plate resting on an elastic pinned subjected to harmonic loads. The plate element model with high-order shear deformation theory and finite element algorithm is proposed in order to buckling analysis of the plate. As a result, the buckling domain is determined. Moreover, the effect of geometric parameters, elastic pins, and materials on the buckling of the plate is comprehensively investigated.

This article investigates the free vibration of the porous metal foam plates resting on an elastic foundation based on the isogeometric approach (IGA). The elastic foundation is modeled as a two-parameter of Winkler and Pasternak foundations. The pores are assumed to vary through the thickness direction in three types: uniform, symmetric and asymmetric distributions.

In this study, the nonlocal elasticity theory is applied to analyze the free vibration of the functionally graded nanobeams. The novelty of the present study is that the classical nonlocal elasticity theory has been modified to take into account the variation of the nonlocal parameters through the thickness of the functionally graded. nanobeams.

The article "Static behavior of FGP half-annular nanoplates resting on elastic foundation using nonlocal elasticity theory" presents an algorithm finite element for static bending analysis of the functionally graded porous (FGP) half-annular nanoplate resting on the elastic foundation (EF) using nonlocal elasticity theory. The FGP materials with two-parameter are the volume fraction index (k) and the porosity volume fraction (5) in two cases of even and uneven porosity. The EF includes Winkler-stiffness (k₁) and Pasternak- stiffness (k₂).
