A Model of Asperity Interactions in Elastic-Plastic Contact of Rough Surfaces

Abstract: This paper presents a micro-contact model incorporating asperity interactions in elastic-plastic contact of rough surfaces. The effect of the asperity interactions on the local deformation behavior of a given micro-contact is first modeled based on the Saint-Venant’s Principle and Love’s Formula. The local contact interference is related in closed form to the local contact load, the global mean pressure and material parameters. This micro-contact model equation is then integrated into the elastic-plastic conta… Show more

“…Therefore, this model is not ideal for analyzing contact in which asperity response is crucial. Zhao and Chang (2001) studied the substrate deformation and asperity interaction in a contact between two nominally flat surfaces by applying a uniform pressure on a square ''territory" of an asperity on the substrate. However, the assumption of uniform pressure on a square area of the substrate in this model does not reflect the real situation for most contacts.…”

“…Many researchers have devoted to analyzing and modeling the contact behavior and calculating the resistance. Several main methods are following, statistical [1][2][3][4], fractal [5][6][7], multi-scale [8][9] and determinist model [10]. The elastic or elastic-plastic deformation is considered in the above models, and the contact condition and material properties are studied, too [11].…”

“…The influence of material behaviour is studied, for elastic perfectly plastic [11] or elastoplastic [12] constitutive equations. The interaction between asperity is also integrated in some models [13,14,15]. Finite Element methods were also used to solve the contact problem between artificial fractal surfaces [16].…”
