A magnetic Barkhausen noise signals are detected when magnetized domain walls move discontinuously in a ferromagnetic material. This non-uniform motion is sensitive to the microstructures of material which vary continuously with the increase of applied loading cycles. In this paper, the process of fatigue damage accumulation subjected to constant cyclic loading are explored by measuring the Barkhausen noise signal with the progress of loading cycles. The experimental results show the possibility to detect the progress of fatigue damage using the peak Barkhausen noise signal.
