Nonlinear Resonance Interaction between Conjugate Circumferential Flexural Modes in Single-Walled Carbon Nanotubes

Figure 21

Contour plot of the total energy distribution Ẽ (η, θ, τ) of the conjugate modes (1,2), (1,2,c) over the SWCNT surface (η, θ). Backward travelling wave from θ = 2π to θ = 0 in the time range τ = (84.57, 84.87). (a) τ = 84.57, (b) τ = 84.63, (c) τ = 84.69, (d) τ = 84.75, (e) τ = 84.81, and (f) τ = 84.87.
