Numerical Modeling of Fretting Wear
In this paper, a review of some techniques proposed in the literature for modelling fretting wear is presented. Fretting wear occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces. Due to the continuous change in the shape of a structure during its lifetime, the design of engineering components subjected to fretting w...
متن کاملA Numerical Study on the Effect of Debris Layer on Fretting Wear
Fretting wear is the material damage of two contact surfaces caused by micro relative displacement. Its characteristic is that debris is trapped on the contact surfaces. Depending on the material properties, the shapes of the debris, and the dominant wear mechanisms, debris can play different roles that either protect or harm interfaces. Due to the micro scale of the debris, it is difficult to ...
متن کاملEvaluation of fretting wear on the femoral stem surface
Fretting wear on polished femoral stems has been well documented in clinical reports, but in vitro simulation to replicate this wear has seldom been attempted and only limited success has been achieved. In the present study, fretting wear was successfully reproduced on the stem surface by incorporating initial stem implantation in a sawbone through bone cement and utilisation of saline solution...
متن کاملInterference Assembly and Fretting Wear Analysis of Hollow Shaft
Fretting damage phenomenon often appears in the interference fit assembly. The finite element model of hollow shaft and shaft sleeve was established, and the equivalent stress and contact stress were computed after interference assembly. The assembly body of hollow shaft and shaft sleeve was in whirling bending load, and the contact status (sticking, sliding, and opening) and the distribution o...
متن کاملFretting wear in self-piercing riveted aluminium alloy sheet
Fretting wear in aluminium alloy AA5754 joined by self-pierce riveting (SPR), a relatively new fastening technique increasingly used in vehicle structures, has been investigated in this paper. Surface damages have been induced when a joint experienced a sinusoidal cyclic tension-tension load. Various degradation zones have been characterised in the contact surfaces between the aluminium sheets,...
