Bifurcation Behavior of Nano and Microbeams

The bistable Micro/Nano-Electro-Mechanical Systems (MEMS/NEMS) based on initially curved micro/nanobeams have drawn more and more attention from the scientific community for their various potential applications such as optical switches, micro-valves and non-volatile memories. The initially curved beam (arch) under transverse forces may exhibit two main instabilities: snap-through buckling and asymmetric bifurcation. We study the instabilities of micro/nanobeams subject to the nonlinear electrostatic force and derive the analytical expressions of snap-through and symmetry breaking criteria, which can be used for the design of bistable MEMS/NEMS.
