摘要
多损伤是老龄飞机最主要的损伤形式,在文中介绍了多损伤应力强度因子的计算方法和多裂纹连通准则,飞机结构多损伤裂纹扩展模型和可靠性分析研究现状。
Multiple site damages（MSD） is the major aging damage forms of aircraft.It was introduced Calculation method of damage stress intensity factor and crack connected criteria for aircraft structure were introduced in this paper,and MSD crack propagation model and situation of its reliability analysis were also presented.
