WebNov 1, 2024 · In the present paper, rotary inertia and small size effects on the free vibration response of single-walled carbon nanotubes are examined. The equations in motion and associated boundary conditions are obtained by using Hamilton’s principle on the basis of modified couple stress and Rayleigh beam theories. The size effect is taken into account … WebThis example shows how to include damping in the transient analysis of a simple cantilever beam. The damping model is basic viscous damping distributed uniformly through the volume of the beam. The beam is deformed by applying an external load at the tip of the beam and then released at time t = 0. This example does not use any additional ...
