| 摘 要： | 本文导出了具有正交异性复合铺层和偏心加筋的圆柱壳体在轴压、横向压力或它们的任意组合作用下的屈曲问题的近似解,文中提出的方法使壳中不同铺层及偏心加筋引起的弯曲与拉伸间的耦合研究成为可能。以前的研究方法表明由于忽略了弯一拉耦合效应,所予测的屈曲结果是不完全正确的。

| Abstract: | In this paper, the approximate solution of buckling problom on cylindrical shells with composite orthotropic and skew ribs under axial pressure, transverse pressure or arbitrary combination of them was studied. The theory of this paper makes it possible to study the bending-stretching coupling effect resulted from the different plies and skew ribs in cylindrical shell. The previous studying methods showed that the neglect of bending-stretching coupling leaded to inaccurate buckling results. |
