Variational principle for non-Newtonian lubrication: Rabinowitsch fluid model. (English) Zbl 1095.76046

The author discusses a semi-inverse method for deriving a one-dimensional Reynolds-type equation by using variational arguments. The key arguments can be extended to other classes of nonlinear equations, including two- or three-dimensional problems and other non-Newtonian lubrications.
