- 摘要：
- This paper deals with the bending of Bernoulli–Euler piezoelectric nanobeams. Unlike the
classical theory, the effect of electrostatic force is taken into account. A variational principle is
employed to derive the governing equations, and the electrostatic force moment is defined. The
electrostatic force moment depends on the piezoelectricity. A cantilever beam problem is
solved. It is shown that the effect of the electrostatic force on the deflection of the beam is
significant when the beam thickness is small, and decreases with increase of the beam
thickness. The results indicate that the deflection of a nanobeam can be modified through the
electrostatic force by adjusting the voltage.
