利用ｖｏｎＫａｒｍａｎ非线性薄板理论，借助Ｔａｙｌｏｒ级数展开方法，求解了３Ｄ复合材料中圆形薄膜脱层的屈曲和后屈曲问题．其中着重分析了横向纤维搭桥约束作用对脱层屈曲性能的影响．大量的计算和分析发现，与无搭桥脱层的特征不同，纤维搭桥不仅起到了抑制脱层演化发展的作用，而且也会导致脱层屈曲模态的突变，从而大大改善了结构性能，提高了结构的剩余强度和使用寿命．
Using von Karman nonlinear thin plate theory, the problem of buckling and post-buckling of the delaminated circular film in 3D composites was solved by means of the Taylor series expansion method. Which focuses on the analysis of the lateral fiber bridging constraints on the delamination buckling performance. Numerous calculations and analyzes show that, compared with the characteristics of non-bridged delamination, fiber bridging not only plays a role in inhibiting the development of delamination evolution, but also leads to the sudden change of delamination buckling mode, thereby greatly improving the structural performance and improving Residual strength and service life of the structure.
