基于Ｚｗｅｂｅｎ［１］的剪滞假设，提出一种修正的剪滞分析模型，研究了层间混杂复合材料低延伸层的断裂、层间界面破坏及高延伸层中部分纤维断裂相互作用所导致的细观应力重分布，讨论了层间界面破坏对高延伸纤维中的应力集中因子的影响，为层间混杂叠层复合材料最终拉伸破坏的细观统计分析提供理论依据。
Based on the shear lag hypothesis of Zweben [1], a modified shear lag analysis model is proposed to study the effects of the fracture of interlaminar mixed composite low-extensional layer, the interfacial interface failure and the partial fiber fracture interaction in the high-extensional layer The influence of interfacial interface failure on the stress concentration factors in high-elongation fibers was discussed. It provides a theoretical basis for the meso-statistical analysis of ultimate tensile failure of interlaminar mixed laminate composites.
