摘要

A refined mathematical framework of high-order surface stresses extended from the conventional surface stresses model is implemented in the mathematical framework for the modeling of buckling load and resonance frequency of nanoplates The high-order interface stresses are formulated following the proposition of non-uniform surface stress across the layer thickness and thereby effectively inducing a membrane stress as well as surface moment In the formulation the deformation of the thin interphase is approximated by the Kirchhoff-Love assumption of thin plate In illustration circular and rectangular nanoplates with simply supported or clamped boundary conditions are exemplified Analytic for numerical solutions of the derived results are compared with the simplified solutions based on conventional surface stress model and on the classical results of linear elasticity We aim to explore the scope of applicability that the refined continuum mechanics model could be a valid approach in the estimate of mechanical behavior of nanoplates
