摘　　要：在文献 [1～ 3]的基础上 ,根据应力变分和伽辽金变分原理导出混合变分方程 ,并将其转换成状态方程 ,使状态空间理论和变分原理相结合 ,给出了正交异性叠层开口柱壳静、动态分析的变分解。此解满足叠层壳的层间连续条件。算例表明 ,本文的方法具有较高的精度 ,并能较准确地计算层间应力。Based on the Refs.[1～3] and according to the stress and Galerkins variational principles, the mixed variational equations are established and then transformed to the state equation. Thus, the theory of state space is combined with variational principles to give the variational static and dynamic solutions for thick laminated open cylindrical shell. The solutions given satisfy continuity conditions between plies of the laminates. The examples illustrate that the present method has high precision, and can be used to calculate the interfacial stresses satisfactorily.
