摘要
基于Miner法则,探讨了不同应力作用顺序时疲劳曲线的变化,分析了大于σ-1的应力对材料疲劳极限的影响,明确了当量应力法和当量循环次数法的使用条件,指出了某些文献对上述问题的模糊认识。
On the basis of Miner theorem, the variation of fatigue curves under different acting sequences of stresses was discussed and the influence of stresses bigger than δ -1 on fatigue limit of materials was analyzed. The prerequisite of application for equivalent stress method and method of equivalent circulation number of times was made clear and fuzzy understandings on the above stated problems by certain documents was pointed out.
