Modeling contact oxygenation and adhesive wear extension in axisymmetric flat circular fretting interfaces

In this study, adhesive wear extension in axisymmetric fretting contacts is simulated by applying the Contact Oxygenation Concept (COC) which illustrates influence of loadings on oxygen transport within interface. Di-oxygen flow modeled using an Advection-Dispersion-Reaction (ADR) approach was formerly proposed assuming third body as a porous medium crossed atmospheric gases. It shown that ADR model not only predictive square but also circular flat interfaces where it capable simulating partition adhesion and abrasion for broad range contact pressures sliding frequencies. Moreover, simplified analytical solution equation proven to be highly correlated with numerical experimental results.
