...Y Gong; M Norton Baseline fatigue data are presented through a series of strain-controlled tension-compression-type fatigue tests on smooth specimens of a Type S1214 mild steel under various combinations of strain amplitudes and nonzero mean strains. The strain magnitudes were chosen in the upper...

... mean strain values of −0.2, 0, and 0.2% were applied in each strain amplitude level. Seven combinations of strain amplitude and mean strain were investigated. It was observed that cyclic softening in the second level was significantly stabilized by the presence of the first level, which accounts...
