Analysis of dynamic pull-in voltage of a graphene MEMS model [PDF]

open access: yesNonlinear Analysis: Real World Applications, 2019
Bifurcation analysis of dynamic pull-in for a lumped mass model is presented. The restoring force of the spring is derived based on the nonlinear constitutive stress-strain law and the driving force of the mass attached to the spring is based on the electrostatic Coulomb force, respectively.
