| description | Moment coupling in fretting fatigue experiments refers to the generation of moments when a shear force is applied,
caused by the difficulty in designing fretting fatigue experiments where the shear is reacted out on the same plane as
the contact. Digital Image Correlation is used to measure the effect of moment coupling, and a model is created to
calculate the effect of the applied moment at any point during a loading cycle on near-edge contact properties. The
effects of the changing contact pressure on the slip zone sizes are considered. Finally, the model derived is used to
find a load cycle including the effect of normal contact force that creates a truly constant near-edge contact pressure
distribution at one edge of the flat and rounded pad. Although the calibrations found in this paper are valid only for the
specific rig and specimen geometry used in this paper, the method could be readily applied to other experiments. |
