Finite element based modeling of multi-asperity contact and validation of Greenwood-Williamson model
The Greenwood-Williamson (GW) model of contact between rough surfaces is a widely acclaimed model that has been used to predict contact stiffness and other contact parameters. A main limitation of this model is often cited as it is ignoring of asperity interaction effects. This thesis aims to …

Modeling of contact between liner finish and piston ring in internal combustion engines based on 3D measured surface
… oil control ring (TLOCR) deterministic model, Greenwood-Tripp correlation function was used to determine contact. The practical challenge for this single equation is that real plateau roughness makes it unreliable. As a result, micro geometry of liner surface needs to be obtained through white …
