Surface Effects of Adsorption-Induced Resonance Analysis of Micro/Nanobeams via Nonlocal Elasticity
摘要
Abstract
The governing differential equation of micro/nanobeams with atom/molecule adsorption was derived in presence of surface effects using the nonlocal elasticity. The effects of nonlocal parameter, adsorption density and the surface parameter on resonant frequency of the micro/nanobeams were investigated. It is found that, in addition to the nonlocal parameter and surface parameter, the bending rigidity and the adsorption-induced mass exhibit different behaviors with the increase of adsorption density depending on the adatom category and the substrate material.关键词
