Deformation, Vibration, Buckling of Continuum Nanotorus

Figure 5

The nanotorus under concentrated loading. The separation displacement can be found as 𝛿 S u n = ( 𝜋 2 / 6 ) ( 𝑃 𝑎 3 / 𝑅 𝐷 ) = 1 . 6 4 4 9 3 4 ( 𝑃 𝑎 3 / 𝑅 𝐷 ) , where bending stiffness 𝐷 = 𝐸 3 / [ 1 2 ( 1 𝜇 2 ) ] , E is Young modulus of the nanotori.
