For prediction of the rupture life of metals subjected to reversed stressing of stress amplitude σa under a constant mean stress σm at elevated temperatures, the linear damage rule was adapted and its rupture life was analized by partitioning of parameter A, or the stress ratio σa/σm. In the range of 0≤A≤1, an equivalent static stress σme for rupture life was determined by use of A and slope αt of rupture life curves based on σm. If rupture life curves of static creep are given, it is possible to predict approximately the rupture life curve of dynamic creep by calculation. In the range of 1≤A≤∞, an equivalent alternating stress σae for fatigue life was determined by using A and slope αt of completely reversed life curves based on σa. Therefore, a fatigue life curve for any mean stress will be predicted analytically from the completely reversed fatigue life curves.
