| Abstract | ||
| Using an analytical approach based on the Galerkin method, a study on the static buckling behavior of functionally graded (FG) laminated shells reinforced with carbon nanotube (CNT) and carbon fibers is presented in this paper. The shapes considered are plate, cylindrical, spherical, elliptical-paraboloidal, and hyperbolic-paraboloidal shells. The variation of the volume fraction through the thickness of the shell is linear, while the percentage of CNT is distributed linearly over all layers of the shell in a constant manner according to four types of configuration: UD, FG-X, FG-O, and FG-V. The influences of various geometrical and material factors on the static buckling of shell structures were then examined using a parametric study. | ||
