Chaudhuri, R.A., Oktem, A.S. e Guedes Soares, C. (2015), “Beam-Column and Tie-Bar Effects in Internally Pressurized Thin Arbitrarily Laminated Cantilever Cylindrical Shells”, Journal of Engineering Mechanics, Vol. 141, pp. 04014131-1 - 04014131-13

An arbitrarily laminated, anisotropic cantilever cylindrical shell of finite length, under uniform internal pressure, is analyzed using Love-Timoshenko's kinematic relations under the framework of classical lamination theory. Extensive numerical results are presented for two model problems, pertaining to two-layer asymmetrically laminated anisotropic cantilever cylindrical shells, illustrating the influence of layer anisotropy and lamination sequence on the beam-column/tie-bar effects, which, in turn, severely affect the free-end displacements and other response quantities of interest. Finally, since the beam-column effect can cause severe wrinkling in a thin asymmetrically laminated cylindrical shell, the possibility of its elimination through composite tailoring (a combination of stacking sequence and fiber orientation angle in a constituent lamina) has also been explored.
