creep-fatigue life

The paper also presents the low cycle fatigue life and creep life's quantificational method of steam turbine's main stop valve and control valve, and applied examples.

提出了汽轮机主汽阀和调节阀阀壳低周疲劳寿命和蠕变寿命的定量设计方法，并给出了应用实例。

The example demonstrates the capacity of the separation of the fatigue-damage and the creep-damage, and the ability to predict the fatigue life with the creep of the polymethylmethacrylate.

算例结果表明，损伤分离法可以分离蠕变疲劳产生的蠕变损伤和疲劳损伤，很好预测疲劳和蠕变共同作用下的疲劳寿命。

Fuzzy judgement method was provided to predict creep fatigue life of turbine blades. Experimantal investigation has shown that the method is feasible and effective.

根据蠕变产生的机理，将工程模糊综合评判方法应用于发动机涡轮叶片蠕变寿命预测，并通过实例验证了该方法的可行性和有效性。
