摘要
疲劳累积损伤规律是疲劳研究中的关键问题之一。现有疲劳累积损伤规律可分为四类,即线性疲劳累积损伤理论、双线性疲劳累积损伤理论、非线性疲劳累积损伤理论和概率疲劳累积损伤理论。每一类理论都有代表性的模型,并各有其优缺点。寻找一个统一的既简单又符合实际损伤发展的疲劳累积损伤规律还是目前疲劳研究中的一个重要课题。
Fatigue accumulative damage rule is one of the most critical problems in the research of fatigue. In this paper, fatigue accumulative damage rules are classified into four categories： linear cumulative damage rule, bilinear cumulative damage rule, nonlinear cumulative damage rule and probabilistic cumulative damage rule. Some representative models of every category are reviewed. Then, their advantages and disadvantages are indicated. It is wished that this paper can be used as a reference to the research of fatigue accumulative damage rules in the future.
