- •
Coupling influences of stress and strain gradients on dynamic pull-in of graded nanotubes reinforced actuator.
- •
As the time history progresses, the phase portrait converges into the center point.
- •
The damping effects increase the pull-in voltage in order to cause dynamic instability of the nano-actuator.
