Abstract
This article presents the buckling behavior of carbon nanotubes reinforced sandwich-structured composite shells supported by elastic foundations. The sandwich-structured configuration is composed of three layers, an isotropic core, and two nanocomposite face sheets. Carbon nanotubes fibers are applied to reinforce nanocomposite face sheets of sandwich composite shells. It is assumed that the distribution of reinforcements across the shell thickness is uniform or functionally graded. Under the assumption of the thin shell, the equilibrium equation of the buckling response of CNT-RSSC shells is obtained. The pre-buckling stresses by applying Airy’s stress function and an adjacent equilibrium criterion to establish the stability equation associated with the buckling state are obtained. The effects of different types of CNTs' reinforcement, volume fractions, geometrical parameters, core to face sheet thickness ratio, and elastic foundations on the mechanical buckling analysis are examined.
期刊介绍:
The scope of the “Gazi University Journal of Science” comprises such as original research on all aspects of basic science, engineering and technology. Original research results, scientific reviews and short communication notes in various fields of science and technology are considered for publication. The publication language of the journal is English. Manuscripts previously published in another journal are not accepted. Manuscripts with a suitable balance of practice and theory are preferred. A review article is expected to give in-depth information and satisfying evaluation of a specific scientific or technologic subject, supported with an extensive list of sources. Short communication notes prepared by researchers who would like to share the first outcomes of their on-going, original research work are welcome.
