In this paper, experimental analysis of ratchetting-fatigue interaction and ratcheting behavior of Ck45 steel were investigated by uniaxial cyclic loading under stress-controled tests. Stress-controled tests performed in two steps in order to evaluate ratchetting strain influence on fatigue life of specimens. First, pre-ratchetting tests were performed with various loading setups and then, their fatigue life were measured in fatigue test with a constant load for all specimens. In uniaxial cyclic loading for stress-control condition, fatigue life of specimens depends greatly on pre-ratchetting stress amplitude and influence of mean stress on fatigue life is limited to a specific mean stress.
