چکیده
|
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.
