A theoretical model for finding the electrical potential values as the stress changes during the fatigue test has been developed. It shows relatively small deviation from the experimental results. The results also indicate that during cyclic loading the changes in electrical resistivity of the material can be neglected. The changes observed in electrical potential primarily represent the geometrical shape change in the test specimen.
