Nonlinear Dynamics of Nanosystems Incorporating Intermolecular Forces

In this research, nonlinear oscillation frequency of adouble clamped nanobeam is investigated throughhomotopy analysis method (HAM). In nanoscale, theeffects of intermolecular forces, such as Van der Waalsand Casimir forces, appear. At first, the governingequation of motion is nondimensionalized. Then it isturned into an ODE by using Galerkin’s decomposition.HAM is used to solve the ODE. The result is validated bythe literature. Then the effects of various parameters onoscillation are studied.
