Abstract
A novel and rigorous ‘inverse hydrodynamic’ approach is described in a companion paper for problems of unsteady elastohydrodynamic lubrication. In it all spatially-distributed quantities are represented by nodal values via finite element discretization. Though the formulation accommodates piezoviscous lubricant models as well as planar, cylindrical, and spherical geometries, it is illustrated here by the prototypical planar example of normal approach of a lightly-loaded rigid indenter to a discretized elastic solid separated by a nearly isoviscous lubricant film. Results from the new ‘nodal’ formulation are compared with those from a previous (and more approximate) ‘modal’ approach to unsteady EHL computation.
