Abstract The aim of this work is to study the initiation and propagation of fatigue cracks during fretting tests in partial slip conditions, and to compare the fretting fatigue behaviour to conventional fatigue C(T) crack growth experiments. An experimental device is specially developed in order to perform in situ fretting fatigue tests at a synchrotron facility. 2D radiographs of fretting fatigue cracks are directly observed in situ for the first time for a cylinder/plane contact configuration. FE computations are carried out to calculate stress intensity factor range Δ K at the crack tip for the complex loading configuration, revealing short and long crack propagation behaviours.
