Research Abstract

A technique to heal fatigue crack was developed to prevent accidents due to aging of structures and improve their fatigue life. As the results, the closure of the fatigue crack and the bonding between the crack surfaces were realized by applying high-density electric current. Decreasing the crack growth rate temporarily was also succeeded. In addition, the delay of fatigue crack initiation was realized due to the decrease of dislocation density. It was found that the technique with the electrical stimulation has the potential to heal a fatigue crack and to restore fatigue damage.
