Load transmission by elastic, elasto-plastic or fully plastic deformation of rough interface asperities

Numerical Modeling of Rough Contact between Two Cylinders with Axes Parallel

“…The contact between two rough cylindrical surfaces is reproduced faithfully. These results led to validate the construction of sum cylindrical surface with the same approach used in the case of flat surfaces [16][17][18][19][20]. It is possible to ensure a perfect equivalence between the results of the two configuration of contact.…”

“…In this respect, Persson et al [15] have developed a stochastic model that excludes the priority of any roughness scale. F. Robbe-Valloire et al [16] study the elastoplastic deformation of nominally flat rough interface, they determined the global load and real area contact of two rough surfaces for a given separation between them. These models do not predict the deformed geometry of rough surfaces in contact and they used a non-standardized parameters.…”

3D Micro-Macro Fluid-Structure Model of Pressure Relief Valve Leak Tightness

“…This technique allows the direct analysis of two contacting surfaces represented into a single equivalent surface in contact with a rigid perfectly flat surface (refer to references [9] and [10]). …”

Effect of Skewness and Roughness Level on the Mechanical Behavior of a Rough Contact

“…The prediction of these quantities is considered to be a necessary requirement to govern several tribological properties and processes such as lubrication, fretting, corrosion and contact vibrations (Sherif 1991). Several models have been proposed in order to describe the behavior of contacting rough surfaces (Greenwood and Williamson 1966, Whitehouse and Archard 1970, Robbe-Valloire et al 2001, Poulios and Klit 2013.…”

“…Later, (Whitehouse and Archard 1970) extended the GW model by considering the asperities curvature distribution. Recently, a statistical model based on the standard procedure for roughness and waviness parameters (ISO12085) has been performed by (Robbe-Valloire et al 2001). This model estimate the load and the real area of an elastic, elasto-plastic and fully plastic contact.…”
