摘要：
Cracking behaviour under fretting fatigue (FF) loading is here investigated. A transparent photoelastic specimen of epoxy is submitted to fretting fatigue conditions. Cracks initiated by fretting contact are shown to propagate up to several millimetres. Qualitative and quantitative informations on fretting crack initiation, location, inclination and growth rate are obtained. Cracks initiate near the edge of the contact. They generally show two principal inclinations. These orientations are related to different propagation stages identified during FF crack life. FF crack growth evolutions are analysed in terms of influencing external loading.
