+Fretting wear: A phenomological approach

An analytical description of fretting wear is proposed wherein the volume of wear debris either removed from the sliding interface or retained within these areas, is represented as a fraction of the freshly-produced debris in each fretting pass. In the proposed model, the volumes respectively of removed debris and of retained debris are tallied over each pass of a fretting sequence to yield a closed analytical expression relating these volumes to the number of passes. The paper provides an example of the adaptation of the proposed model to experimental wear data on steel-steel fretting interfaces.
