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.
