计算结果表明，复合地基是否具有应力扩散的效应受很多因素影响，如加固层的几何性质、荷载分布的几何性质等。
It can be seen from the results that the properties of stress dispersion of composite ground are affected by many factors, such as geometrical properties of reinforced layer and load.
本文结果为进一步研究正交叠层复合材料的细观破坏机理、最终拉伸强度及协同效应等提供了重要的理论依据。
The present results may provide an important theoretical basis for further studying the micro-failure mechanism, ultimate strength and synergistic effect for cross-ply laminates under tension.
而裂纹板经复合材料补片胶接修补后，平行于裂纹方向的拉压应力对裂纹尖端的应力强度因子具有耦合效应，并且这种耦合效应的大小与补片的铺层含量有很大的关系。
While with a composite patch, there exists coupling effect between the normal stress parallel to crack and the SIF, and the coupling effect is significantly dependent on ply orientation of the patch.
