JANGHORBAN, Maziar  e  ZARE, Amin. Harmonic differential quadrature method for static analysis of functionally graded single walled carbon nanotubes based on Euler-Bernoulli beam theory. Lat. Am. j. solids struct. [online]. 2012, vol.9, n.6, pp.633-641. ISSN 1679-7825.  http://dx.doi.org/10.1590/S1679-78252012000600001.

Bending analysis of functionally graded single walled carbon nano tubes is presented in this paper. Carbon nano tubes are modeled as Euler-Bernoulli beam theory in this study. Harmonic differential quadrature (HDQ) method is used to discretize the governing equations. In order to show the accuracy of present work, the results are compared with those of other existing results. Then the effects of different parameters such as power law index, inner and outer radius of nano tubes and length nano tubes of are studied, too.

Palavras-chave : Functionally graded nanotubes; Euler-Bernoulli beam theory; Harmonic differential quadrature method; Static analysis.
