Abstract

Abstract– The ability of mesh design in arbitrary Lagrangian-Eulerian finite element method
(ALE-FEM) makes it a generally efficient device for simulating engineering problems. In this
paper, ALE-FEM is used to model the static deflection and instability of beam-type cantilever
nano-actuators using plain element. Effects of electrostatic fields are taken into account through
first-order fringing field corrected model. In addition, the influence of quantum vacuum
