In this paper the fretting fatigue evaluation was carried out to determine the effect of bolt clamping on the
failure mode and the fatigue life of double shear lap joints of aluminum alloy plates 2024-T3 at different
levels of the longitudinal stress. Regardless the stress amplitude, when the tightening torque is relatively
lower the mechanical fatigue failure occurred at the edge of the bolt hole, and the fatigue life increased
with the tightening torque. When the bolt clamping is increased further, the fretting wear failure occurred
near the bolt hole due to the gross sliding of the specimen surface, and the fatigue life increased with the
increase in tightening torque. A bolt clamping boundary between the fretting failure and the mechanical
fatigue increased with increasing longitudinal stress.
