Nonlinear Theory of Sandwich Shells with Strong Orthotropic Core,
Abstract
A geometrically nonlinear theory of sandwich shells with strong orthotropic core is presented. The principle of minimum energy is used to derive the equilibrium equations and the natural boundary conditions of the composite shell. The theory takes the flexural rigidity as well as transverse shear deformation of the core into account, while including, as usual, the flexural rigidities of the facings. The core layer of the sandwich shell is of orthotropic material having symmetry with respect to two orthogonal planes. The equations of equilibrium and boundary conditions are simplified for the sandwich shells of revolution. Finally the cylindrical, conical, ogival, and the shallow spherical sandwich shell equations are given and their methods of solution are discussed. (Author)
