Dynamic pull-in instability of electrostatically actuated beams incorporating Casimir and van der Waals forces

Abstract In this study, influences of intermolecular forces on the dynamic pull-in instability of electrostatically actuated beams are investigated. The effects of midplane stretching, electrostatic actuation, fringing fields, and intermolecular forces are considered. The boundary conditions of the...
