Work on analysis of the common structural shell element made of composite materials is very extensive. Contributions will be mentioned that parallel the developments in Chapter 5 on plates. Some of the first analyses of laminated shells are by Dong, Pister, and Taylor [6-44] and the monograph by Ambartsumyan [6-36]. Further efforts include the buckling work on laminated shells by Cheng and Ho [6-45] and on eccentrically stiffened laminated shells by Jones [6-46].

A rectangular plate with dimensions Ipx x Ipy = 18.0 x 9.0 m stiffened by a rectangular beam of 1.0 m width eccentrically placed with respect to the center line of the plate (Fig. 4) has been studied (damping ratio = 1 = 0). In Table 1 the torsion 7 and warping 7 constants of the beam cross section and the values of the primary warping function (4>s)ff (/ = Ij 2) at the nodes of the two interface lines for various beam heights are presented. In Table 2 the computed first five eigenfrequencies, in Fig. 5 the fundamental modeshape and in Fig. 6 the deflection time history at point C (Fig. 4) of the stiffened plate for the cases of a partial in both directions and a full shear connection...
