Numerical Analysis of Geometrical Parameters Effect on Contact Zone Under Fretting Fatigue Loading

Autor: Mohamed Ikhlef Chaouch, Abdelghani Baltach, Ali Benhamena

Publikováno v: Advances in Materials Science. 22:5-20

The fatigue process under fretting conditions is characterized by small oscillatory movements due to vibrating or cyclic loads between two surfaces in contact. Two phenomena can arise as a consequence: the surface wear of the bodies in contact, givin
