- •
The structural response of an electrostatically-actuated single-walled carbon nanotube (SWCNT) actuator is investigated.
- •
A nonlinear Galerkin model taking into consideration the SWCNT rippling deformations as well as the Casmir forces is derived.
- •
The SWCNT rippling deformations along with the Casimir attractive forces were shown to alter its static and dynamic stability.
- •
Results were compared with experimental and molecular data and therefore the integrity of the numerical analysis were verified.
