(a) Total strain energy of a nanotube with $R=6.26\mathrm{\AA }$. (b) Bending moment $M$ vs bending angle. (c) Elastic bending moments in the plates of the kink varying with the bending angle. (d) Work done (energies) in the kink mechanism, where $W_1$ is the work done in flattening of the triangular regions, $W_2$ is the work done in flattening of the circular region, $W_3$ is the work done in rotation about hinge line $AC$, $W_4$ is the work done in rotation about hinge lines $AE$, $CE$, $AF$, $CF$, $W_{\mathrm{vdW}}$ is the work done by the van der Waals force, and $W$ is the total work done.
