Abstract

Building upon the successful treatment of several tribological degradation phenomena within the unifying thermodynamic framework, this chapter presents a robust predictive methodology specific to the analysis of fretting fatigue crack nucleation. A thermodynamically based continuum damage mechanics approach is adopted along with surface and subsurface stress fields as well as a nonlocal averaging technique to simulate the progressive accumulation of microdamage near the contact area. General agreement between the predictions and the experimental observations for both smooth and rough surface contacts confirms the ability of the current technique to predict fretting fatigue crack initiation behavior. In addition, due to its inherent benefits, the framework presented here is believed to have a high potential to be extended for the analysis of crack nucleation in several other contact problems.
