A técnica de multi grelha na solução de problemas de lubrificação Elasto HidrodinâmicaThe multi-grid technique in solving Elasto Hydrodynamic lubrication problems
(Universidade Federal de UberlândiaBrasilPrograma de Pós-graduação em Engenharia Mecânica, 2020)
Friction characterization when combining laser surface texturing and graphite-based lubricants
(ELSEVIER, 2020)
The present work analyzes the friction capabilities at room temperature of three types of lubricants (denoted as A, B and C) with a graphite concentration of 5%. To do that, the standard pin -on disc test is deployed to ...
Numerical solution of a 2D lubrication model with Sommerfeld boundary conditions for hip prostheses
(Springer, 2015-01)
Prosthetic in-contact surfaces wear is one of the main causes of hip replacements fallure. Lubrication is essen- tial to reduce the friction and consequently the wear. A two- dimensional model based on a modified Reynolds ...
Moving textures: simulation of a ring sliding on a textured liner
(ElsevierAmsterdam, 2014-04)
Numerical simulations of the ring/liner contact in which the liner exhibits a periodic texture (pockets)
are reported. The mass-conservative Elrod–Adams model is used to treat cavitation, and the dynamics
of the ring is ...
Numerical micro-texture optimization for lubricated contacts — a critical discussion
(Springer, 2022)
Despite numerous experimental and theoretical studies reported in the literature, surface micro-texturing to control friction and wear in lubricated tribo-contacts is still in the trial-and-error phase. The tribological ...
A Lagrangian reproducing kernel particle method for metal forming analysis
(Springer VerlagNew YorkEUA, 1998)
Multi-scale surface patterning to tune friction under mixed lubricated conditions
(Springer Nature, 2019)
It is well accepted that the tribological performance of surfaces can be directly correlated with their energy efficiency and lifetime. Consequently, surface patterning has gained great attention to manipulate friction and ...
