An approach based on film buckling under simple uniaxial tensile testing was utilized in this paper to quantitatively estimate the interfacial energy of the nanostructured multilayer films (NMFs) adherent to flexible substrates. The interfacial energies of polyimide-supported NMFs are determined to ...

单壁碳纳米管的力学性能、断裂和屈服行为与其几何形貌的关系

新型炭材料 doi:10.1016/S1872-5805(11)60091-7

采用分子动力学模拟研究了单壁碳纳米管的力学特性与其长度、直径及手性的关系.在施加拉伸或压缩载荷时,不同直径的单壁碳纳米管表现出明确的力学性能变化.锯齿型和扶手椅型碳纳米管的拉伸性能与其长度无关,而对于手性碳纳米管来说则稍有变化.所有类型碳纳米管的压缩特性,主要是刚度和临界压应力均随碳纳米管长度的变化...
