Molecular dynamics analysis on buckling of defective carbon nanotubes.
Owing to their remarkable mechanical properties, carbon nanotubes have been employed in many diverse areas of applications. However, similar to any of the many man-made materials used today, carbon nanotubes (CNTs) are also susceptible to various kinds of defects. Understanding the effect of defects on the mechanical properties and behavior of CNTs is essential in the design of nanotube-based d...
متن کاملInvestigation of Vibrational Behavior of Perfect and Defective Carbon Nanotubes Using Non–Linear Mass–Spring Model
In the present study, the effects of arrangement and distribution of multifarious types of defects on fundamental frequency of carbon nanotubes are investigated with respect to different chirality and boundary conditions. Interatomic interactions between each pair of carbon atoms are modeled using two types of non–linear spring–like elements. To obtain more information about the influences of d...
متن کاملMolecular Dynamics Simulations of Strained and Defective Carbon Nanotubes
Carbon nanotubes are tubular molecules of pure carbon with typical diameters of 1 nm – 100 nm and lengths from 100 nm up to several cm. The nanotubes have outstanding electronical and mechanical properties which has resulted in remarkable scientific interest and in proporsals of various applications. For example, their ability to be either metals or semiconductors enables the usage of nanotubes...
متن کاملBuckling of defective carbon nanotube
Carbon nanotube (CNT) has attracted enormous attention from researchers since its discovery in 1991. Due to their remarkable mechanical properties, carbon nanotubes have been employed in many diverse areas of applications including biological probes, atomic force microscopy and also in nanocomposites. However, similar to any of the many man-made construction materials used today such as steel a...
متن کاملBuckling of Double-walled Carbon Nanotubes
This paper is concerned with the buckling of double-walled carbon nanotubes (DWCNTs) under axial load. The DWCNTs are modelled as two cylindrical shells, one shell nested in the other and Winkler springs are introduced to connect them in order to simulate the van der Waals forces between the two nanotubes. By using the Donnell thin shell theory, we derive the governing equations for the bucklin...
