linear fatigue cumulative damage rule 线性疲劳累积损伤理论
The results show that the cumulative damage of propellants under the different stress levels agrees with linear rule.
结果表明，在不同应力水平下，推进剂的累积损伤基本符合线性累积损伤规律。
But the common linear fatigue damage cumulative rule neglects the fatigue damage which is brought by the high frequency and low stress.
一般的线性损伤累积理论忽略了高频率低疲劳应力所引起的构件疲劳损伤，致使预测结果与实际寿命相差很大。
