Fatigue Damage Threshold Value 疲劳损伤界限
damage threshold value 损伤门槛值
threshold value of damage 损伤阈值
damage life threshold value 损伤寿命门槛值
The initially existing damage has apparently affected on wave stress propagation and stress distribution as long as its quantity exceeds a threshold value.
当初始损伤超过某临界值后会显著地影响应力波的波动范围和围岩应力分布；
The threshold value of damage and maximum strain are adopted as failure criterion to reflect fatigue failure and ductile failure respectively.
针对材料不同的失效模式，分别采用损伤变量门槛值和最大应变作为失效判据。
Finally the threshold value of load amplitude that influences fatigue life of wheelset is calculated based on the principle of equivalent damage and damage distribution agreement.
依据损伤等效和损伤分布一致原则，计算得出了影响轮对疲劳寿命的载荷幅值门槛值。
