In this paper, the relation between the fatigue lives and the plastic strains during all of the fatigue lives was investigated under the double stresses on the 0.55C carbon steel. When the primary stress σ_1 is larger than the secondary stress σ_2,the plastic strain on the secondary stress ε_<p2> is larger than the plastic strain on the mono stress level ε_p, and ε_<p2><ε_p for σ_1<σ_2,and this phenomenon is analogous to the phenomena of the fatigue lives under the double stresses. Moreover, the phenomena of the plastic strains during all of the fatigue lives on the secondary stress are very different from those on the mono stress level. The relation between the elastic hysteresis energy and the fatigue life under the double stresses was also investigated.
