Abstract :
In this paper, the nonlinear forced vibration of isotropic viscoelastic/ piezoelectric EulerBernoulli nanobeam is investigated. For this purpose, the consistent couple stress theory is utilized for modeling the viscoelastic/piezoelectric nanobeam. Hamilton’s principle is also employed to obtain the governing equations of motion. Further, the Galerkin method is used in order to convert the governing partial differential equations to a nonlinear secondorder ordinary differential one, and then multiple scale method is used to solve motion equation.
