This study simulated an experimental campaign on an Al 7075-T6 aluminium alloy to investigate fretting fatigue behavior. A multiaxial fatigue criterion was used to simulate a flat-to-flat bridge-shaped contact under different fatigue loading conditions.
In the last decades, many catastrophic events due to the rupture of metallic components have been traced back to fretting fatigue. In order to avoid failures due to such a contact phenomenon, many researchers have focused on fretting fatigue behaviour of different materials. In the present work, an experimental campaign carried out on an Al 7075-T6 aluminium alloy is simulated by employing a multiaxial fatigue criterion proposed for fretting fatigue. The configuration simulated is a flat-to-flat bridge-shaped contact, characterised by cyclic normal load, with different frequencies, as well as different levels of fatigue loading applied to the specimen.
