Autor: X. Gómez, M.A. Urchegui, W. Tato, Alaitz Zabala, Iñigo Llavori

Publikováno v: Theoretical and Applied Fracture Mechanics. 101:294-305

This work presents a numerical procedure for combined fretting wear and fretting fatigue problems. It combines the Archard wear model and the Smith-Watson-Topper fatigue indicator parameter with the Miner damage rule for crack nucleation estimation.

Publikováno v: Tribology International. 143:105988

This work presents a critical analysis of coefficient of friction derivation methods for fretting under gross slip regime. A mass review of tribology journals revealed that 41% of papers did not specify the derivation method used and 37% employed the
