The fatigue mode of material removal of alumina ceramics under cyclic stress was analyzed. Synchronized biaxial repeated indentation technique simulate the alternating stress state in repeat pass sliding. Debris generation mechanism through fatigue grain failure was confirmed and the contact induced surface degradation due to fatigue cracking accumulation was quantified by measuring contact displacement. Variation of structural compliance was expressed as a variation of the apparent elastic properties of the contact system.
