Abstract

This paper studies the bending behavior of nanoplates, incorporating the effects of surface stress andnonlocal elasticity. Thin and moderately thick nanoplates embedded in an elastic medium are analyzed. The complete governing equations, including both the effects of surface stress and nonlocal elasticity, are derived, while the solution for bending is solved by Navier’s approach. The analytical solution in this study could serve as a benchmark in the evaluation of future research. Based on the results of this study, the opposite influence of surface stress and nonlocal elasticity on the bending of nanoplates is observed. Various parametric studies are investigated to elucidate the combined effects of surface stress and nonlocal elasticity.
