An all-in-one numerical methodology for fretting wear and fatigue life assessment
Many mechanical components such as, bearing housings, flexible couplings and spines or orthopedic devices are simultaneously subjected to a fretting wear and fatigue damage. For this reason, the combined study on a single model of wear, crack initiation and propagation is of great interest. This p...

| description | Many mechanical components such as, bearing housings, flexible couplings and spines or
orthopedic devices are simultaneously subjected to a fretting wear and fatigue damage. For this reason, the
combined study on a single model of wear, crack initiation and propagation is of great interest. This paper
presents an all-in-one 2D cylinder on flat numerical model for life assessment on coupled fretting wear and
fatigue phenomena. In the literature, two stages are usually distinguished: crack nucleation and its subsequent
growth. The method combines the Archard wear model, a critical-plane implementation of the Smith-Watson-
Topper (SWT) multiaxial fatigue criterion coupled with the Miner-Palmgren accumulation damage rule for crack
initiation prediction. Then, the Linear Elastic Fracture Mechanics (LEFM) via eXtended Finite Element Method
(X-FEM) embedded into the commercial finite element code Abaqus FEA has been employed to determine the
crack propagation stage. Therefore, the sum of the two stages gives a total life prediction. Finally, the numerical
model was validated with experimental data reported in the literature and a good agreement was obtained. |
