Abstract
In this paper, static bending and buckling behavior of the simply supported truncated sandwich conical shell with variable thickness core are examined. The stiffness of the system changes as a result of changes in the porous core’s thickness, which varies along the generator direction. Additionally, there are five various styles of porosity distribution schemes for the porous foam core that are taken into consideration. Hamilton’s principle, FSDT and Galerkin method are utilized to obtain a set of matrix equations for calculating the deflections and critical buckling loads of the system under thermal environment. The static properties and mode are investigated.
