摘　　要：根据Ｈｅｌｉｎｇｅｒ－Ｒｅｉｓｓｎｅｒ变分原理，在柱坐标系中，导出叠层开口柱壳的弱形式混合状态方程和边界条件，给出了叠层开口柱壳的解析解。Weak formulation of mixed state equation including boundary conditions is presented in a cylindrical coordinate system by introducing Hellinger Reissner variational principle. Analytical solutions were obtained for laminated open cylindrical shells. The present study extends and unifies solution of laminated open shells.
