High performance structures require the use of different materials to meet their demanding requirements. Especially fibre reinforced polymer composites are nowadays often bonded to metals in order to take the most advantage of the materials properties and to minimize their disadvantages. However, the interface in such bi-material assemblies often represents the weakest point and thus has to be carefully addressed to ensure structural integrity. This review paper presents an overview of the research on bi-material interface crack problems over the past 30 years. Three categories of the research are discussed: mechanical testing, crack driving force and mode partitioning. The literature reveals that the key element to the fracture analysis of the bi-material interface crack is how to perform the mode partitioning. The proposed theories for mode partitioning by many researchers are meaningful yet underdeveloped and need further experimental validation.

高性能结构需要使用不同的材料来满足其苛刻的要求。如今，尤其是纤维增强的聚合物复合材料经常与金属结合，以充分利用材料性能并最大程度地减少其缺点。但是，这种双材料组件中的界面通常代表最薄弱的环节，因此必须小心处理以确保结构完整性。本文回顾了过去30年中双材料界面裂纹问题的研究概况。讨论了三类研究：机械测试，裂纹驱动力和模式分配。文献表明，双材料界面裂纹断裂分析的关键因素是如何进行模式划分。
