| 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内的应力传递的影响,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: | Based on the secant modulus method and Weibull statistic law, a micromechanical method is advanced to model the matrix plastic deformation and the particulate cracking for metal matrix composites during straining. The influences of the particulate mean size and its scatter on the composite macroscopic behavior are analyzed in details.It is found that the particulate mean size plays a key role in the composite damage properties.The theoretical results for a SiC P/Al composite agree well with the experimental ones in the literature. |
