Deterministic Modeling of Two-Body Abrasive Wear and Friction Relationships
| While related at the asperity scale, friction and wear are rarely coupled in numerical models due to the trouble with most statistical contact mechanics in tracking actual asperity interactions. This project focuses on deterministically modeling of each asperity interaction between two sliding surfaces. While simulating the contact mechanics at each asperity junction using real material properties, surfaces are allowed to naturally evolve while predicting both friction and wear.
