The nonlinear mechanical response of carbon nanotubes, referred to as their "buckling" behavior, is a major topic in the nanotube research community. Buckling means a deformation process in which a large strain beyond a threshold causes an abrupt change in the strain energy vs. deformation profile. Thus far, much effort has been devoted to analysis of the buckling of nanotubes under various loading conditions: compression, bending, torsion, and their certain combinations. Such extensive studies have been motivated by (i) the structural resilience of nanotubes against buckling, and (ii) the substantial influence of buckling on their physical properties. In this contribution, I review the dramatic progress in nanotube buckling research during the past few years.
碳纳米管的非线性力学响应，即其“屈曲”行为，是纳米管研究领域的一个主要课题。屈曲是指这样一个变形过程：超过阈值的大应变会导致应变能与变形曲线发生突变。到目前为止，人们在分析纳米管在各种加载条件下的屈曲方面投入了大量精力：压缩、弯曲、扭转以及它们的某些组合。这些广泛的研究是由以下两点推动的：（i）纳米管抵抗屈曲的结构弹性，以及（ii）屈曲对其物理性质的重大影响。在本论文中，我回顾了过去几年纳米管屈曲研究取得的显著进展。
