✦ Synopsis

This paper proves the generalized compatibility of the boundary displacement pattern of the generalized conforming ¯at shell element with drilling degrees of freedom and the central line displacement pattern of the beam element with Hermite interpolation. According to the incremental equation of virtual work of the three dimensional (3D) continuum, the UL formulations of the 3D beam elements and generalized conforming ¯at shell elements with drilling DOFs are used for geometrical non-linear analysis of composite stiened shell structures. Here the concentric stiener is assumed to be isotropic. A number of numerical examples are given to demonstrate the eectiveness of the proposed approach.
