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...

Abstract This paper presents a novel approach to developing 2D structural theories for composite shells. The proposed uses the capabilities of Carrera Unified Formulation (CUF) in conjunction with Axiomatic/Asymptotic Method (AAM) obtain best given layouts. Different cases are considered analyze influence factors such as boundary conditions, lamination, and thickness on accuracy model. paramete...

Currently, lattice composite structures have many applications in aerospace industries. The present research analyzed the effect of an external skin consisting of a lattice’s cylindrical shell on the buckling strength of composite materials, both numerically and experimentally. Two classes of specimens, with and without external skins, were fabricated using the filament winding process. To find...
