脱层的存在将会大大降低层合结构的屈曲载荷。利用含环向贯穿脱层壳的屈曲分析模型 ,对各种算例进行分析。首先通过与经典理论和一阶剪切理论结果的比较 ,验证了分析模型的正确性 ,指出了它们各自的适用范围。考虑了脱层壳的三种不同屈曲模态。分析了不同径厚比、边界条件及脱层长度、深度、位置对脱层壳屈曲载荷的影响。最后给出了正交各向异性脱层壳的屈曲分析以及铺层角度对脱层壳屈曲载荷的影响
The presence of delamination will greatly reduce the buckling load of the laminated structure. Various examples were analyzed by using the buckling analysis model with circularly penetrating delaminated shells. First of all, through the comparison with the classical theory and the first-order shear theory, the correctness of the analysis model is verified and their respective applicable scopes are pointed out. Three different buckling modes of delaminated shells are considered. The effects of different aspect ratio, boundary conditions, delamination length, depth and position on the buckling load of delaminated shells are analyzed. Finally, the buckling analysis of orthotropic delaminated shells and the effect of ply angle on the buckling load of delaminated shells are given.
