The tensile strengths of individual multiwalled carbon nanotubes (MWCNTs) were measured with a "nanostressing stage" located within a scanning electron microscope. The tensile-loading experiment was prepared and observed entirely within the microscope and was recorded on video. The MWCNTs broke in the outermost layer ("sword-in-sheath" failure), and the tensile strength of this layer ranged from 11 to 63 gigapascals for the set of 19 MWCNTs that were loaded. Analysis of the stress-strain curves… 

On the tensile strength distribution of multiwalled carbon nanotubes

Individual multiwalled carbon nanotubes grown by chemical vapor deposition (CVD) were tensile tested within the chamber of an electron microscope using an atomic force microscope-based technique.

Nanobeam Mechanics: Elasticity, Strength, and Toughness of Nanorods and Nanotubes

The Young's modulus, strength, and toughness of nanostructures are important to proposed applications ranging from nanocomposites to probe microscopy, yet there is little direct knowledge of these

Brittle and Ductile Behavior in Carbon Nanotubes

The field of carbon nanotubes has seen an explosive growth in recent years due to the substantial promise of these quasi-1D structures for potential uses as highstrength, light-weight materials,

Mechanical relaxation and “intramolecular plasticity” in carbon nanotubes

The question of how carbon nanotubes (CNT)—believed to be the strongest filaments—relax under tension has been addressed. A dislocation theory applied to a two-dimensional nanocrystal such as the CNT

Electrostatic deflections and electromechanical resonances of carbon nanotubes

The methods developed here have been applied to a nanobalance for nanoscopic particles and also to a Kelvin probe based on nanotubes, which indicates a crossover from a uniform elastic mode to an elastic mode that involves wavelike distortions in the nanotube.

Buckling and Collapse of Embedded Carbon Nanotubes

Recent experimental and theoretical results [1 ‐ 9] suggest that carbon nanotubes hold great promise as a possible reinforcing phase in composite materials of a new kind. Such developments still

Graphite whiskers have been grown in a dc arc under a pressure of 92 atmospheres of argon and at 3900°K. They are embedded in a solid matrix of graphite which builds up by diffusion of carbon vapor

Mechanical properties of vapour-grown carbon fibres

Vapour-grown carbon fibres are formed by depositing layers of carbon from hydrocarbon pyrolysis on precursors of filamentous carbon. They are partially graphitic with the basal planes preferentially
