STATIC BENDING ANALYSIS OF FGP L-SHAPE NANOPLATES RESTING ON ELASTIC FOUNDATION USING FEM BASED ON NONLOCAL THEORY

Abstract

This article presents a finite element method for static bending analysis of the functionally graded porous (FGP) L-shape nanoplate resting on the elastic foundation (EF) using the nonlocal elasticity theory. The FGP materials with two-parameter are the volume fraction index (k) and the porosity volume fraction (ξ) in two cases of even and uneven porosity. The EF includes Winkler-stiffness (k₁) and Pasternak-stiffness (k₂). Some numerical results of the proposed method are compared with those of published works to verify accuracy and reliability. Furthermore, the effects of some elastic foundation factors and material properties of static bending of FGP nanoplates resting on the EF are studied in detail.
