本文根据复合材料加筋壳的材料特性，获得了环肋、纵筋、斜筋和三角形网格加筋壳的广义刚度系数，从而将圆柱壳与加筋壳的稳定性问题统一起来。并利用Donell壳体理论，推导了在外压作用下，复合材料加筋圆柱壳总体失稳的临界压力公式。可供有关工程设计师参考。
The article concludes the generalized stiffness of shells withring and vertical, inclined and triangular stiffeners on the basis of the material features of composite stiffened cylindrical shells, which unifies the stability between cylindrical shell, and stiffened shell and that derives the buckling critical pressure of composite stiffened cylindrical shells under external pressure from Donnell-type theory which can be for reference by engineers
