Effect of Geometrical Parameters on Tensile Properties of Nanotubes
There is a large variation of mechanical properties, such as Young’s moduli for nanotubes as indicated from both experimental and theoretical studies. From an early study , the experimental values of Young’s modulus of the carbon nanotubes was 1.3 −0.4/+0.6 TPa. While, in another study  measured value for Young’s modulus of nanotubes as 0.816 ± 0.41 TPa. The wide variation in the experimental results may be due to the several factors including (i) presence of defects in nanotube specimens and (ii) inherent limitations of current experimental techniques.
