Four Node Flat Shell Quadrilateral Finite Element for Analysis of Composite Cylindrical Shells
This work presents the free vibration and static analysis of laminated composite cylindrical shells with a 2D computationally efficient facet-shell finite element that is formed by combining the plate bending and membrane element. The element is based on zigzag theory and is augmented using the discrete Kirchhoff quadrilateral element developed earlier by the second author for the analysis of composite and sandwich plates. It is vital to convert the actions and displacements from local to global direction using a transformation matrix. DKZigTS is developed by adding two fictitious degrees of freedom and has nine local and global degrees of freedom per node. It does not face the problem of the ill-conditioned stiffness matrix. The performance of the developed element is assessed for its exactitude by comparing the results obtained with analytical 2D, 3D and finite element solutions available in the literature. Various boundary conditions, geometrical shapes and material properties are used in this study. The element exhibits a very satisfactory performance for moderately thick and thick shell panels.
