  • How to determine the number of asperity peaks, their radii and their heights for engineering surfaces : a critical appraisal
    Pogačnik, Aljaž, 1985- ; Kalin, Mitjan
    At present there are no generally accepted and experimentally confirmed, 2D or 3D, deterministic, asperity-deformation models to evaluate the real contact area in tribological applications. One of ... the key obstacles is that there are no clear and experimentally verified criteria about how to define and consequently determine the actual load-carrying asperity peaks. As a result, this work attempts to clarify how different, arbitrarily selected, asperity-peak identification criteria affect the calculated asperity-peak properties, i.e., the number, radii and heights. Such an analysis is still missing from the literature on 2D and 3D, asperity-peak analyses and is required for a better understanding of the physical meaning and engineering feasibility, and thus more realistic assumptions about these criteria.
