Nonlinear buckling of eccentrically stiffened nanocomposite cylindrical panels in thermal environments
Abstract Based on Reddy's third order shear deformation shell theory and Galerkin method, this paper introduces analytical solutions to study nonlinear buckling behaviors of imperfect carbon nanotube reinforced composite cylindrical panels on elastic foundations in thermal environments. The panels are reinforced by single-walled carbon nanotubes and the eccentrically longitudinal and transversal stiffeners. The effects of geometrical parameters, eccentrically stiffeners, elastic foundations, initial imperfection, temperature increment and nanotube volume fraction on the mechanical behaviors of the nanocomposite cylindrical panels are also examined in numerical results. Some comparisons with results of other authors show the accuracy of the present theory and approach.
Highlights Nonlinear buckling of nanocomposite cylindrical panels. The initial imperfect, panel – foundation interaction and temperature dependent properties are taken into account. The panels are reinforced by eccentrically longitudinal and transversal stiffeners. The Lekhnitskii's smeared stiffeners technique and the Galerkin method are used. Effects of the carbon nanotube, stiffeners, elastic foundations are considered.
