THE GEOMETRICALLY NONLINEAR THEORY OF ANISOTROPIC SANDWICH SHELLS FACED WITH LAMINATED COMPOSITES
( Department of Mechanical Engineering, Wuxi University of Light Industry Wuxi, Jiangsu 214036, P.R. China )
By using spline functions, a unified expression to describe various continuous or discontinuous variables in sandwich shells and laminated shells is derived. Then a general nonlinear theory of anisotropic sandwich shells faced with laminated composites is developed using the assumption of a smooth layer-wise curvilinear coordinate
after deformation. The theory combines the global theory and the discrete-layer theory of laminated shells in view of the structural characteristics of anisotropic sandwich shells faced with laminated composites. A series of refined theories for sandwich and laminated shells can be obtained directly by simplifying the general theory.
