Numerical measures of non-proportionality degree in incomplete contact subjected to fretting fatigue loading Reza H. Talemi ArcelorMittal Global RD Gent-OCAS N.V., Pres. J.F. Kennedylaan 3, 9060 Zelzate, Belgium. Email address: reza.hojjatitalemi@ Abstract Fretting fatigue failure is a fatigue fracture that initiates at a surface area where fretting has occurred. Fretting fatigue life assessment under multiaxial loading is a rather complex task, as the stresses at contact interface are multiaxial. A phase-shift between stress components leads to lower equivalent stress values calculated by most of available multiaxial fatigue criteria
