Radial elastic corrugation of multiwalled carbon nanotubes under hydrostatic pressure is demonstrated by using the continuum elastic theory. Various corrugation patterns are observed under a pressure of several GPa, wherein the stable cross-sectional shape depends on the innermost tube diameter D and the total number N of concentric walls. A phase diagram is established to obtain the requisite values of D and N for a desired corrugation pattern among choices. In all corrugation patterns, the cylindrical symmetry of the innermost tube is maintained even under high external pressure.
利用连续介质弹性理论证明了多壁碳纳米管在静水压力下的径向弹性波纹。在几吉帕的压力下观察到了各种波纹模式，其中稳定的横截面形状取决于最内层管的直径D和同心壁的总数N。建立了一个相图，以在多种选择中获得所需波纹模式下D和N的必要值。在所有波纹模式中，即使在高外部压力下，最内层管的圆柱对称性也得以保持。
