Pull-in instability of nano-switches using nonlocal elasticity theory

摘要: This paper investigates the pull-in instability of nano-switches subjected to an electrostatic force due applied voltage and intermolecular within framework nonlocal elasticity theory account for small scale effect. Both nonlinear governing equation boundary conditions with effect are derived. A linear distributed load model is proposed approximate interactions. Closed-form solutions critical parameters obtained cantilever fixed-fixed nano-beams. The freestanding behaviour nano-beams, which a special case in absence force, also studied. It found that contributes nano-beams quite different ways. effects gap ratio, slenderness ratio discussed detail as well.
