To some extent the way the computation is carried out is governed by the objectives. Usually information about one or more of the following is sought pressure distribution in the lubricant film minimum thickness of the film shape of the film. Items of input into the problem are load, radii of curvature of the boundaries, material properties (such as viscosity and density of the fluid together with their pressure and temperature dependence, elastic constants of the solid boundary material), and speed. A set of assumed initial conditions is used to 

It is very cumbersome to investigate the influence of the various parameters by full solution of the elastohydrodynamic problem over an ex- 

Cheng [13] reported that for nearly pure rolling (U = U2) there was no significant thermal effect on either the pressure level or the film thickness, but for cases involving moderate or high slip the temperature
