The Small Scale Effect on the Dynamic Behavior of Cantilever and Fixed-Fixed Nano-Switches

Abstract

Abstract-Based on the conventional Euler bucking model and the effective nonlocal elasticity theory, the dynamic behaviors of cantilever and fixed-fixed nano-switches are studied in this paper. The governing equations for the dynamic response of the nano-switches including small-scale effect are derived by using the energy variational method. The small-scale effects on the stiffness of nano-switches are presented. It is found that the scale effect has softened the fixed-fixed nano-switches and hardened the cantilever nano-switches.Index Terms-Scale effect, cantilever nano-switch, fixed-fixed nano-switch, effective nonlocal elasticity.
