Proc. ASME. IMECE2012, Volume 3: Design, Materials and Manufacturing, Parts A, B, and C, 677-683, November 9–15, 2012
Paper No: IMECE2012-86522
... In order to investigate the complex contact behaviors of micro-rough interfaces, this paper proposed a novel finite element method (FEM) for simulating the contact between two rough surfaces. The numerical methods for generating Gaussian and non-Gaussian rough surfaces were introduced...

Proc. ASME. IMECE2008, Volume 7: Emerging Technologies; Recent Advances in Engineering, 79-94, October 31–November 6, 2008
Paper No: IMECE2008-68488
... 24 08 2009 Three dimensional elastic-plastic contact of two nominally flat rough surfaces is considered. Equations governing the shoulder-shoulder contact of asperities are derived based on the Chang, Etsion and Bogy (CEB) model of contact in which volume conservation is assumed...

... Mechanical Engineering Congress and Exposition October 31-November 6, 2008, Boston, Massachusetts, USA E1 DUCTION seminal work of Greenwood and Williamson [1] enwood and Tripp [2] established the early models tic contact of nominally flat rough surfaces. These have been used extensively in the realm of y...

... Three dimensional elastic-plastic contact of two nominally flat rough surfaces is considered. Equations governing the shoulder-shoulder contact of asperities are derived based on the asperity-asperity constitutive relations from a finite element model of their elastic-plastic interaction...

Paper No: IMECE2007-43615
... 26 05 2009 It is reasonable to expect that when two nominally flat rough surfaces are brought into contact by an applied resultant force, they must support, in addition to the compressive load, an induced moment. The existence of a net applied moment would imply non-even distribution...

... surfaces. Each is described as a statistical summation of the micron-scale interaction of the surfaces. The model is shown to provide accurate prediction of bulk temperature using a dynamometer test on a carbon composite disk pair. friction heat rough surface asperity elastic force Proceedings...

Paper No: IMECE2003-41536
... 14 05 2008 This paper studies the bistable nature of the hydrophobic contact angle on the rough surfaces. It was experimentally shown that a droplet of liquid can liquid can form two different contact angles on a surface that has roughness patterns. External disturbances can cause...
