Analytical modeling of buckling of carbon nanotubes reinforced sandwich-structured composite shells resting on elastic foundations

This article presents the buckling behavior of carbon nanotubes reinforced sandwich-structured composite shells supported by elastic foundations. The configuration is composed three layers, an isotropic core, and two nanocomposite face sheets. Carbon fibers are applied to reinforce sheets sandwich shells. It assumed that distribution reinforcements across shell thickness uniform or functionally graded. Under assumption thin shell, equilibrium equation response CNT-RSSC obtained. pre-buckling stresses applying Airy’s stress function adjacent criterion establish stability associated with state effects different types CNTs' reinforcement, volume fractions, geometrical parameters, core sheet ratio, foundations on mechanical analysis examined.
