For efficient cargo space in a global range transport aircraft, a noncircular cross-section fuselage is investigated. The cross-section investigated is a rectangle with rounded corners. In order to minimize the resulting bending stresses, sandwich construction is investigated, and in particular a mid-plane asymmetric construction is studied to utilize bending stretching coupling to minimize these bending stresses still further in the sandwich construction. Traditionally, in almost all cases of sandwich constructions to date, the construction is mid-plane symmetric, i.e. the faces are of the same material and thickness. There are many needs for sandwich constructions using different faces. For example, for a racing boat, one face is subjected to corrosion, the other face is primarily subjected to an internal environment. On the other hand, considering that many advanced composite materials have different strengths and elastic moduli in tension and compression, even if the two faces are made of the same material, different face thickness can provide a superior structure. The governing equations are obtained by applying the Theorem of Minimum Potential Energy and displacements are assumed. Solutions are derived for a non-circular shell, involving a mid-plane asymmetric sandwich construction that are subjected to a constant internal pressure for the structure with flat sides and rounded corners. The shell is simply supported at both ends. Solutions are obtained through piece-wise matching of plate and shell sections.

“…5 Later on, valuable results for elastic behavior of sandwich cylindrical shells were published by Preisner and Vinson. 6 Finally, Jaskula and Zielnica 7 presented an analysis for elasto-plastic stability of sandwich cylindrical panels. In all above reported works, no plastic deformations were allowed in the core of the sandwich shell.…”

In this paper, static response of a sandwich cylindrical shell under elasto-plastic deformation is investigated. The faces are made of some isotropic materials and the core is made of an orthotropic material both with linear work hardening behavior. The faces are modeled as thin cylindrical shells obeying the Kirchhoff-Love assumptions. The core material is modeled as a special orthotropic solid in which its in-plane stresses are assumed to be negligible. The Prandtl-Reuss plastic flow theory and von Mises yield criterion are used in the analysis. The governing equations are derived using the principle of virtual displacements. Using Ritz method, the equations are solved for deformation components. After verification of the results, the analysis is extended by changing the values of different parameters.
