The classical theory of contact focused primarily on non-adhesive contact where no tension force is allowed to occur within the contact area, i.e., contacting bodies can be separated without adhesion forces. Several analytical and numerical approaches have been used to solve contact problems that satisfy the no-adhesion condition. Complex forces and moments are transmitted betw… Web6 apr. 2024 · DOI: 10.1108/ilt-11-2024-0336 Corpus ID: 257992064; Tribological behavior of different doped ta-C coatings for slip-rolling contacts with high hertzian contact pressure @article{Polzer2024TribologicalBO, title={Tribological behavior of different doped ta-C coatings for slip-rolling contacts with high hertzian contact pressure}, author={Markus …
