| 摘 要： | 本文用有限元法研究了具有基体裂纹的纤维增强复合材料内的应力传递问题。假设纤维与基体的界面为非理想的，文中运用“弹簧层”模型首先分析了在不同的组分弹性模量比、纤维体积含量与边界约束条件下，界面相性态对复合材料的应力传宾影响，然后进一步考察了在几种典型的损伤模式下界面附近的应力分布情况。

| Abstract: | Using finite element method, the stress transfer in a matrix cracked fiber reinforced composite is studied. The interface between fiber and matrix is assumed to be non ideal and is simulated by a spring like layer. The effects of interphase properties on the stress transfer are analyzed for different ratios of elastic moduli, volume fractions of fibers and for various boundary conditions. The stress distributions near the interphase are also investigated under several typical modes of damage. |
