TL;DR: In this paper, a simulation approach for journal bearings operating from hydrodynamic to mixed lubrication regime where severe metal-metal contact occurs is presented, and the simulation results in the form of Stribeck curves provide a solid base to prove the isothermal elastohydrodynamic simulation approach.

TL;DR: In this article, an elastohydrodynamic (EHD) calculation using an extensive oil-model and including an approach to the conformal roughness of the bearing surfaces is carried out for transient loads typical for current utility vehicles (40MPa) as well as for considerably higher specific loads (70 MPa) and for different lubricants (SAE10, SAE20,SAE30 and SAE40) to account for a large span of working conditions.

TL;DR: In this paper, the impact of the piezoviscous effect and non-Newtonian lubricant properties on the friction power losses in journal bearings over a wide range of dynamic loads and shaft speeds was investigated.

TL;DR: In this paper, the half-metallic ferromagnet was analyzed in combination with local and non-local many-body correlation effects for a variational cluster approach and finite-temperature dynamical mean field theory.

TL;DR: In this article, the authors focus on the beginning phase of hydrodynamic journal bearing life time when the first adaption of the contacting surfaces occurs, known as running-in.
