Elastohydrodynamic lubrication of faults
The heat flow paradox provides evidence that a dynamic weakening mechanism may be important in understanding fault friction and rupture. We present here a specific model for dynamic velocity weakening that uses the mechanics of well-studied industrial bearings to explain fault zone processes. An elevated fluid pressure is generated in a thin film of viscous fluid that is sheared between nearly ...

متن کاملStabilized Finite Elements for Elastohydrodynamic Lubrication Problems
In this work, we are mainly interested in modelling a particular lubrication regime known as Elastohydrodynamic (EHD). The pressure generated in the conjunction is high enough to induce a significant elastic deformation of the contacting bodies. Therefore a strong coupling between hydrodynamic and elastic effects is involved. A finite element full-system approach is used to model the lubricant ...

متن کاملElastohydrodynamic Lubrication With Herschel-Bulkley Model Greases
The analysis of grease-lubricaled rolling element bearings i s presented. Exferimen tally determined flow curaes for grease are found to be well correlated by the Herschel-Bdkley model flow eqzration. A theory for predicting roller Jilm thickness based on the assumed flow model i s derived. Experimental results show that grease will deveIop a larger film lhickness lhan the grease base oil at ji...
