For low cycle number (low test duration up to 20000 cycles) the wear kinetics evolution induced by fretting
is linear with an important removal of the upper layers that is related to the accommodation phenomenon of the displacement at the interface.
It is well known, that fretting
arises wherever two components in contact are subjected to small relative displacement amplitude, whereas the reciprocating sliding wear is known to occur at much larger displacement amplitude.

After many days and years, after multitudinous suns had risen and set and risen again, after expending like a Croesus of time, most of the days and nights granted a sojourner, after fretting
and moiling and losing his way and his temper (and now and again as it seemed, his soul) -- at long last our peregrine did a simple thing -- a thing that might have occurred to a wiser one, as the first thing of all to be done.
Carnwath, I suspect, knows that her nonart ideas - her philosophical thumb-suckers, her Eastern mysticism, her fretting
over ecology, her generalized upset with violence, misogyny, intolerance, and the whole caboodle of things she calls "bad stuff" - demand some kind of subtlety of presentation if they are not to seem hopelessly adolescent.
