摘要
功能梯度材料是一种新型材料。功能梯度材料的断裂力学分析属于非均匀材料断裂力学范畴。从裂纹尖端应力场和裂纹扩展两个方面,阐述了功能梯度材料弹性断裂分析的研究方法和主要结论。
The functionally gradient material is a class of new material. Fracture analysis of FGMS belongs to the scope of nonho-mogeneous materal fracture mechanics. The research methods and main conclusions of FGMS fracture analysis are reviewed from the aspects of asymptotic fields near the crack tip and crack expansibility.
