A mixed lubrication model for studying tribological behaviors of surface texturing
TL;DR: In this article, an analytical numerical model was developed to understand the tribological behavior of textured surfaces in mixed lubrication regime, which employed the average flow Reynolds equation and an elasto-plastic contact model, established on the basis of finite element analysis, to calculate the hydrodynamic pressure in full film region and the contact pressure in contact region, respectively.

Asperity micro-contact models as applied to the deformation of rough line contact
Ali Beheshti,Michael M. Khonsari +1 more
TL;DR: Different statistical microcontact models including Greenwood-Williamson (GW), Chang-Etsion-Bogy (CEB), Zhou-Maietta-Chang (ZMC), Kogut and Jackson-Green (JG) are employed together with the bulk deformation of the bounding solids to predict dry rough line-contact characteristics such as the apparent pressure profile, contact width and real area of contact as discussed by the authors.

On the Modeling of Elastic Contact between Rough Surfaces
Robert L. Jackson,Itzhak Green +1 more
TL;DR: In this article, the authors used several measured profiles of real surfaces having vastly different roughness characteristics to predict contact areas and forces from various elastic contact models and contrast them to a deterministic fast Fourier transform (FFT)-based contact model.

Theory of elasticity
TL;DR: The theory of the slipline field is used in this article to solve the problem of stable and non-stressed problems in plane strains in a plane-strain scenario.
Journal ArticleDOI
Contact of Nominally Flat Surfaces
TL;DR: In this article, the authors proposed a new theory of elastic contact, which is more closely related to real surfaces than earlier theories, and showed how the contact deformation depends on the topography of the surface, and established the criterion for distinguishing surfaces which touch elastically from those which touch plastically.

The Contact of Two Nominally Flat Rough Surfaces
J. A. Greenwood,J. H. Tripp +1 more
TL;DR: In this article, the authors give a general theory of contact between two rough plane surfaces and show that the important results of the previous models are unaffected: in particular, the load and the area of contact remain almost proportional, independently of the detailed mechanical and geometrical properties of the asperities.

Elastic-Plastic Contact Analysis of a Sphere and a Rigid Flat
Lior Kogut,Izhak Etsion +1 more
TL;DR: An elastic-plastic finite element model for the frictionless contact of a deformable sphere pressed by a rigid flat is presented in this paper, which provides dimensionless expressions for the contact load, contact area and mean contact pressure, covering a large range of interference values from yielding inception to fully plastic regime of the spherical contact zone.
