摘要
整体复合材料件越来越多地被用作现代航空航天器的主承力结构,而分层是其最易出现的破坏形式。本文作为整体复合材料结构分层特性综述的第三部分,重点介绍了分层试验、屈曲分层、扩展准则和疲劳分层研究。首先总结了各种复合材料分层试验方式和能量释放率计算公式;其次,总结了不同研究者提出的分层扩展准则、疲劳分层裂纹扩展速率计算公式及近些年的研究成果;同时,对近几年屈曲分层研究进行了简要概括。
The integrated composite structures are is suitable for the principle bearing structures of aircraft,and delamination is the most common failure mode. This paper is the third part for the overview of delamiantion characteristics of integrated composite structures. The contents in this paper were focused on delamiantaion test,buckling delamiantiong,growth criterions and fatigue delamination. First,the different test styles and formulas for strain energy release rate were summarized. Second,the delamiantion growth criterions,growth rate and research results by different author were introduced. At last,the author summarized the results of buckling delamiantion in recent years.
