Nonlinear behaviour of carbon nanotube-based resonators

Abstract eng:
In the present study, a new size-dependent nonlinear model is developed for analyzing the behaviour of carbon nanotube-based resonators. Molecular dynamics simulation is then performed in order to parametrize and validate the size-dependent continuum model at the nano scale. The equations of motion are discretized by means of the Galerkin technique and solved employing the pseudo-arclength continuation technique. A new universal pull-in formula is also developed for predicting the voltage corresponding to the static pull-in.
