Specimens from BS L65 4 percent cooper alloy were tested under cyclic tension and static compression. The constant compression was used to reproduce the fretting damage on the specimen surface. It was shown that the place of the fretting damage has not regular disposition on the specimen surface were the fatigue crack has initiation. The fatigue striations were seen on the second stage of the crack propagation. The special methodology was applied to the crack growth analysis in the case of the biaxial stress-state with R=-1.0 for the investigated material. The fretting influence on the fatigue crack propagation was estimated on the bases of the functional correction, F(fr), for the stress intensity factor, KI. The fretting damages influence on the fatigue crack growth have been briefly discussed on the bases of the reproduced from the fractographic analysis kinetic curves and on the bases of the calculated functional corrections F(fr) for different cases studied of the material stress-states.
