RISStatic behavior of nano/micromirrors under the effect of Casimir force, an analytical approach
numerically and analytically using the homotopy perturbation method (HPM).
It is observed that with increasing the instability number defined in the paper, the rotation angle of the mirror is increased and suddenly,
pull-in occurs. Since...
Influence of Van der Waals force on static behavior of nano/micromirrors under capillary force
limits of the nano/micromirror. It is also found that rotation angle of the mirror due to capillary force highly depends on the vdW force applied to the mirror. Finally, analytical tool Homotopy Perturbation Method (HPM) is utilized for prediction...
Nonlinear free vibration of simply supported beams considering the effects of shear deformation and rotary inertia, a homotopy perturbation approach
The objective of this paper is to apply He's homotopy perturbation method (HPM) to analyze nonlinear free vibration of simply supported Timoshenko beams considering the effects of rotary inertia and shear deformation. First, the equation governing...
