Lubricated elastoplastic contact model for metal forming processes in OpenFOAM

A lubricated contact model with elastoplastic asperity deformation and compressible modified Reynolds equation is presented. The model is implemented into foam-extend, a community driven fork of OpenFOAM and used as a solid contact boundary condition for the hyperelastoplastic finite volume deformation solver. The changes of the lubricant rheology properties are taken into account, as well as the deformation of asperities. The modified Reynolds equation is tested on two cases: journal bearing and half cylinder with a sliding plate. The complete lubricated contact model is tested on a wire drawing case using three different asperity contact models, and the results are compared to the standard penalty model.
