摘要
本文分析了复合材料的界面断裂问题，阐述了有关界面裂纹的基本概念，并对界面裂纹的力学模型进行了比较和归纳，最后讨论了用断裂力学参量Ｇ＿ｃ和Ｋ＿ｃ评估界面结合强度的有效性及一般原则。
Some basic Problems concerning interface fracture of composites,especially ofbimaterial combination,and questions resulting from the assumption of different boundaryconditions of interface crack models are discussed.Commonly used analytical formulas areunified and different models are summerized and compared by relating well- know parametersused in the discription of an interface,Finaly an availability of using Kc-concept to evaluatethe bonding strength of different material combinations is presented.
