摘要
介绍了近十年来颇受关注的疲劳多裂纹(MFC)问题的研究.其研究的对象主要是长寿命承力结构,尤其是老龄飞机;目的是建立疲劳多裂纹问题裂纹扩展的计算模型和含疲劳多裂纹结构的失效准则.该研究为长寿命承力结构的疲劳可靠性评定奠定了基础.
Multiple Fatigue Cracks problem, which includes widespread fatigue damage problem and multiple site damage problem, is currently a focus of many studies. It is introduced in this paper. The objective of this research is to deal with aging structures, mainly aging airplane structures, to establish a computing model of multiple fatigue cracks problem and a failure criteria of multiple fatigue cracks structures. This research lays down a base for assessing fatigue reliability of the aging structures.
